| solids in a hydraulic block? -- Mike McQuesten, 10/01/2001
Okay FE fans here's one for you. John Saxon and I were looking under the hood of an old '58 Wagon I keep stashed with all the other Fairlanes/Comets/Mercs & Galaxies stashed on the back acre of my little plot-o-earth. This rusted out old hulk of a Country Sedan was assembled in October of '57.It has a 352 "Police Interceptor". The first three months of production for '58, all 352/332s came factory equipped with Shell solid lifters and the weakest sister cam you can imagine. I don't believe this engine has ever had the heads off. The little locking tabs are still in place on the ex. manifold bolts even. And they're locked on very well. But I have taken off the intake just to see what I can find. Also has the machined combustion chamber heads too. I've pulled out all the original shell lifters and little parts, i.e, pathetic 5/16" X 10.6" pushrods.
So here's our question and it's no test, we really would like to know why this block looks like a hyddraulic block? We speculate that the early FEs o '58 may have been cast ready to run with hydraulics but for some odd reason...the hydraulic cam/lifter/rockers weren't ready?? The oil hole is drilled in the lifter bores. The holes are there in the main gallery line and plugged but I haven't removed the top plugs yet to see whether the lower ones might be plugged. Could it be possible that Ford chose to run the Shell lifters to block unnecessary oil flow in these early blocks?
If that were the case, wouldn't running shell solid lifters, with the right cam of course, be the way to convert a hydraulic engine to a solid lifters & cam? The dumbbell solids would let the oil flow which is of course a real waste of oil flow.
By the way, I did run a 428 CJ with a Schneider solid lifter cam and dumbbell solid lifters. I'd run a couple of cams that I didn't like so went with the solid stick for a couple of years before switching back to hydraulics/cam. I know it's not the smartest thing to do but I had no problems. It would rev to 6,500 but it was useless since it was done around 6,000 so that's where I kept my shift points.
So our point is....are shell solids the way to go with a hydraulic block that you don't want to pull and drill and tap for plugs? |
| | RE: solids in a hydraulic block? -- gerald, 10/01/2001
yes i use them in all my fe's with no truble but get your push rods from fomosports take an old one to get the right one i bleve they are 300 six but they are the right linth and moley hard so they work well by the way 427 super hipo used shells they are lighter so easyer rpm's |
| | | RE:thanks, but what I was asking.. -- Mike McQuesten, 10/02/2001
Thanks Gerald, yes, I'm aware that the shell lifters work fine. And that they were part of a "Rev Kit" Ford offered for the 427FE because they're lighter than the standard dumbells. And I've asked before about preferences and received a lot of good advice.
But what I really want to know is...
Would the shell lifters be a good choice to use if you want to run a solid lifter cam in a hydraulic FE engine? Not because they're lighter, etc. But because you don't want to or can't do the proper conversion of blocking off the oil passage to the hydraulic lifter bores. Would the Shell lifters block oil flow? Which I know is a good thing when running a solid lifter cam.
Anyone? |
| | | | RE:Okay, I think -- Mel Clark, 10/03/2001
Mike, when I worked at H -M we often put the B7 lifters in the Hydraulic block when changing to a solid lifter cam. Never had a problem that I was aware of, neither Ford or H - M even suggested blocking the oil passage to the lifters when changing. As aside note, the 427 engine came with 3 different solid lifters with the shell type being introduced in that engine as part of the 7000 RPM kit. The other lifters were the "Dumb Bell" type and the last being almost as heavy was cast with little hollowed out pockets and had a spiral built into the side them, probably to help promote rotation on the cam as both of the heavy lifters had wear problems |
| | | | | RE:Okay, I think -- Mike McQuesten, 10/03/2001
Thanks Mel, you've affirmed our theory that a hydraulic FE block can run a solid lifter cam fine especially with the shell style lifters. As I said, I did run dumb bells in my 428 CJ for a couple of years. On the street mostly and on the strip regularly. Stock CJ pan too but with six quarts of oil being moved by a high volume Mellings oil pump.
I've not seen the third style of solid lifer you've mentioned. Of course, there's a lot I haven't seen...yet. But I keep lookin'!
I have an odd set of FE solid lifters: Iskenderian's. When I bought my '60 Sunliner 352/360 from a guy who had owned it since '62, he told me he'd changed cams around '63/'64 to an Isky. I got the original Ford cam/lifers from him too. I removed the Isky cam from the 352 and sure enough, it's an 505B Hardface. I've got an Honest Charley Catalog from '64 that gives the specs. Pretty radical cam. But the lifters were the oddity. They look very similar to a standard hydraulic lifer except they're not. No oil hole/plunger. Just a rock solid lifter.
I t might be a neat cam to use for a drive in cruising thumper but I'm leary on the early syle of cam retiner, i.e., thrust button/spring and timing cover. A weal link in early HP FEs. The cams were prone to "walking".
Thanks again. |
| | | | | | RE:Okay, I think -- Mel Clark, 10/03/2001
There were several marketers of the lifter you described and they did work fine, just a bit heavy. Nearly everyone I knew back then ran the B7 light weight lifters from Ford trucks and the super skinny push rods. Ther were several companys that made lifter conversion kits where you disassembled the lifter and installed a solid spacer in place of the hydraulic unit, they worked too but were also heavy. The B7 lifters seemed to be a secret 'til long after the 427s were using them, for some reason. |
| '67 Shelby 428 "pings" under load...need help -- Steve Boulay, 10/01/2001
I've tried several timing/tuning senarios. I've eliminated all vacuum advance (I'm not running original centrifugal only distributor). Set centrifugal to 20 deg. of crank rotation, initial as low as 4deg. for a 24 degree total that's all in by 2500 rpm. I still get a know a part throttle load and at full throttle. My question is, ...... do I have the centrifugal curve comming in too fast? I can't seems to get the ping to go away completely w/o doses of LS130. I'd prefer not to use additives...... Combination suggestion, timing curve insights, overall ignition solutions/suggestions will be appreciated.... Thanx, in advance Steve Boulay |
| | RE: '67 Shelby 428 "pings" under load...need help -- Morgan, 10/01/2001
Steve, I do remember recurving my stock Distributor. I think total added up to 36. Its hard to remember, its been a few years. Last year I got so ticked off with the stock dual four set up that I ended up pulling it off and installing a 750 holley on top of a Holly Dominator intake. It does not look as good but, it Runs so much better. |
| | You need vacuum advance. -- Royce Peterson, 10/01/2001
Steve,
Centrifugal advance distributors are dumb for the street. They don't know anything except RPM. So if you set one for best performance at the strip it will ping like crazy under load on the street.
If you want it to run decent on the street a vacuum advance distributor is the only way to go short of installing a computer controlled knock sensor system. Get a good condition stock distributor, add a Pertronics points eliminator kit. Limit initial plus mechanical advance to the area of about 34 degrees or so. Remember that the vacuum advance is all gone at WOT because there is little or no vacuum. The vacuum advance should supply another ten degrees or so. Accel makes a nice adjustable vacuum advance unit, the Motorcraft units can also be adjusted using washers to limit advance. The vacuum advance will tailor your ignition advance curve based on load for the best possible street performance.
Now if you have lots of spare time and money MSD offers a knock sensor which can be used to retard the timing automatically in the event of detonation / spark knock. There are a variety of ways to implement this, check with MSD for your options if this is interesting to you.
I am running an MSD 6AL ignition with a stock vacuum advance distributor converted as I described above on one of my 427 stroker motors. It is magnificent under all conditions and the rev limiter saves the motor if I do anything stupid like miss a shift.
Good Luck, Royce Peterson |
| | | RE: You need vacuum advance. -- Steve Boulay, 10/01/2001
Royce, Thanks for the quick reply, and I agree with what you've said. The distributor I have has a Pertronix ignitor and an adjustable vaccuum advance canister, but have it disconnected because it makes the pinging worse. I've always run between 34-38 degrees total before(on other engines), but can't seem to get this one sorted out. I'm not sure exactly what the compression ratio is, and I'd like to give up on the lead additive. Is there a "better" brand of pump gas I should be using? Also, my original question related to the 'rate' that the centrifugal advance comes in and the rpm that total happens at. Do you think that slowing that down with heavier springs and putting more/less into the advance weights will affect the "pinging" appreciably? Also, I'm using ported vaccuum to run the advance canister(when it's connected),..... will full manifold vacuum afford much of a difference in this area? Any additional thoughts will be appreciated. SGB |
| | | RE: You need vacuum advance. -- Steve Boulay, 10/01/2001
Royce, By the way,....do you have a source of info. on the MSD knock sensor type ignition controls?? I can't seem to find that anywhere. thanx, SGB |
| | | | RE: You need vacuum advance. -- Royce Peterson, 10/01/2001
Steve,
There is probably a point where if you have way too much compression combined with a mild cam that the pinging would be impossible to get rid of. Have you ever measured cold cranking pressure? Mine is about 210 PSI.
I tried all kinds of fuel additives and my personal opinion is that none has any significant effect. I tried Techron, Outlaw, 104 and Real Lead brands among others. If you really want to improve your gasoline a mixture of 50 percent 110 octane race gas with 50 percent super unleaded works wonders. I can run another 5 degrees initial .
Also, don't worry too much about the actual number of degrees. Try adjusting the timing until the ping is gone for the fuel being used. That's all that really matters.

| | | | RE: You need vacuum advance. -- Royce Peterson, 10/01/2001
Steve,
MSD does not sell the knock sensor itself, you have to use one from a late model Ford or GM in conjunction with the MSD#8982 Start / Retard single stage timing retard control. This unit has a control circuit which needs a ground to complete the circuit to trigger a preset amount of ignition retard. The knock sensor provides a ground to trigger the unit. Different modules plug into the retard control to provide the retard level desired. You must also have a MSD 6 or 6AL unit.
MSD also makes a variable timing control that has a simple knob to control timing, this might also be an option for the techno geek FE lover. Once again you need a 6A or 6AL MSD box to plug into.
All this is a lot of work, expense and complexity compared to the vacuum advance unit. I like them best connected to the ported vacuum on the carb. Mine is an 8V setup so the hose is connected to the front carb.

Unless you have a new vibration dampner (and even if you do) you should check that to be sure the outer ring that has the timing marks hasen't moved. I always put a paint mark on the inner and outer portion of the dampner as I had a similar problem years ago. The engin just wouldn't stay in time, according to my timing light. |
| 390GT-true High Performance -- Mike McQuesten, 09/30/2001
I appreciated Don V.'s stand-up for the 390GT. He made some good points in support of the often maligned FE-GT. Don offers some E.T./mph facts from Car & Driver, 3/66. I don't want to sound too skeptical but 14.2 and 13.98 from a GTA Fairlane and Cyclone GT respectively. That may be the most positive test(s) ever on a stock 390GT.
The best magazine test I had ever read was fromSuper Stock and drag illustrated, January 1966. Fast Eddie Schartman ran a supposedly stock '66 Cyclone GT 4 speed car to a best of 14.09 at 98.36 mph. This car was equipped with 4.11s, 7" slicks, hurst shifter and some other suspension tweaks to get this time.
I bought a Fairlane GTA new in May, 1966. I beat every "standard" model of '65-'66 muscle car I raced. My 'lane was low optioned, no PS/B or air. It had 3.25 limited slip with the new C-6 Select Shift automatic. First time at the strip, Kent Pacific Raceways, Seattle, it ran a best of 15.00 at 97 mph. This was in C pure stock. I won my first two races against a '66 442 and a '66 GTO. Both standard 4V cars. Then I ran a '65 GTO tri powered 389/4 speed. In pure stock classes there was no differenitation based on transmissions. This was my first loss in over a month of owning the car. I continued to beat base muscle cars, 325 horse 396s were no problem. Same with 383 Mopars all the way into '68 with 'runners & bees. I really njoyed beating those. But when it came to 360/350/375 horse 396s, tri powered 389s, up-level 400 Ponchos, it wasn't a race. I saw nothing but taillights disappear into the dark night on those narrow country roads. But I'd race 'em all.
In '69 , I added a 428 P.I. intake and a dual point distributor. The 390 GTA would now run consistently in the mid 14s. Still with stock 3.35 gearing. I had to drive it regularly rain, sleat or snow. It was my main car for ten years. Sold it foolishly in '76 for a whopping $1,400. Excuse me while I stand up here and kick my self in the ass for the umpteenth time.
Okay, that always makes me feel better. So what do I really think of a 390GT? The C6OZ-6250-B cam & corresponding lifters/valve springs were a nice up grade to the trusty workhorse. The Holley 600 was an occasional leaker but it looked cool with the chrome air cleaner, rocker covers,dip stick and let's not forget the clutch fan. A guy or gal could drive it regularly with very few problems. You could cruise, go to college, work and to the drag strip for a healthy dose of humiliation.
Here's what the Dearborn engine engineers should have made a case to the bean counters for:
A step up- could of been called the 390GT-High Performane. Mustang GT had it! The little 'stang had a nice peppy 225 horse 4V 289 standard. The enthusiast could choose a real Hi Po with the 271 horse combo. The Fairlane GT had a smooth & peppy 335 horse 390 but where was the 'Lane's High Performance option? Hmmm, no where.
They had it. The 1965 390-330 horse Police Interceptor. It had a good solid lifter cam with 282 degrees of duration. The cam was the right shaft to go with the tri power option that had worked so well from late '61 into '63 on both 390 & 406s. This cam was the same one that got carried into '66 for the 428 Police mill. It worked fine with sticks or automatics. The better police rods? Easy. The C6AE-R heads would have been fine too. So it wouldn't have been too expensive & exotic like the brute 427. The blocks could have been cast along with the '66 428 PI blocks. Maybe rated around 350-360 horses. Tri Power & Solids, it'd been been a legend just like the best 390 ever built, the '61/401 horse.
Please don't take my opinions the wrong way. I really like any car that came stock with a 390 GT be it Fairlane, Comet, Mustang or Cougar. I just think you have to "work 'em" to make them competitive. I've got a spare '67 390 stashed in the corner. I might just build my vision of the GT-High Performance someday. Find me another 'lane/'lone or maybe a S code 'stang and ....

| | They came loaded for bear... -- Don V, 09/30/2001
Excellent post Mike, If you get a chance to read the C/D mag you will find it entertaining. The Fairlane rolled off a Holman Moody car carrier, and the Comet had arrived in the company of Bud Moore's crew, these guys obviously were instructed by Dearborn to win this shootout by any means necessary and they didn't fool those who knew better. The following is a paragraph describing the Comet: "The Comet bordered on the ludicrous. It came off the line like a Super Stock, surging up on it's haunches under power exactly like a NHRA stocker It's engine was an ostensibly stock stock 390 cubic inch Ford - the same prosaic old workhorse that has loyally powered the Thunderbird for so many seasons. Anyone who knows engines will tell you there isn't a 390 built that will turn more than 5300 - 5500 rpm in stock form, but the ones in our Comet and Fairlane would turn an effortless 6500 rpm. " As I said before I am no fan of old magazine tests and this test is a prime example of why, but I sure would have liked to have seen the look on the faces of the Royal Pontiac crew when the Comet was off loaded from the transporter with the name of Bud Moore emblazoned on the sides - as the popular commercial intones - priceless. Again your post is most informative and an interesting read. Oh and by the way don't feel alone about having regrets selling your Fairlane, I practically gave away a factory delivered 66 2dr bare bones Custom 428PI 4sp big Ford on trade in for a 68 Cougar XR7 302, at the time I felt the Ford wasn't " cool enough". |

| | RE: .80 over 390 = 406==help -- Mike McQuesten, 10/01/2001
So what are you building? A 406 replica? You must have a need to make this a 390/406, right?
It's tough to advise you to go ahead and bore that C6ME-A block .080 without having it sonic tested/mapped. The markings you indicate "may" make it a great candidate but how do you know? Look at the thread right by this one about taking a '70s era 360 block out to 4.13 bore. You just can't tell.
And as for the 391 FT block. Again, it's very likely that it's also a great candidate. But I would still want it sonic checked. My 391 FT block is a C6ME (No A or other markings like yours). We found the little tiny 428 cast numbers visable through the middle core plug hole. I still had it sonic checked/mapped. Because of what we found, it's now bored .030 over 428. I have the Ford distributor bushing. It should make a great performance block.
So you're going to run the 352/390 HP heads, COAE-D? With the other '61 HP equipment, it sounds like you're building the 401 horse replica.
I've done something somewhat similar with a '63 427 block using all Ford parts to make a pseudo 352HP. I can't hide the cross bolts but not many will know to look anyway. Those who do look deserve to know the truth. They're FEnatics like us! |
| 360 to 428cj? possible? -- MustangRacer'67, 09/29/2001
I have checked on many message boards about building a 428cj out of a 360 truck block. I have heard this IS possible, because the 360 and 390 are the same block as the 428cj. I was told I need to get the block checked, bored, and throw in the 428 parts. Does anyone here know alot about the 360 or 428? Anyone have any comments, ideas, problems? I want to check this out with as many people as I can before I invest any $. Thanks in advance! |
| | RE: 360 to 428cj? possible? -- richard, 09/29/2001
the 360 was built using a 352 rod and crank with a 390 piston. a 428 crank would go in and with the stock bore you would get 410 ci. the stock 390 bore is 4.05 where as the stock 428 bore is 4.13. if the block passes a sonic check you could bore it .08" but since you can build the 410 for much less money and give more rebuilds i would do that instead. if you really want a 428 then i say find a 428. |
| | | RE: 360 to 428cj? possible? -- MustangRacer'67, 09/29/2001
But it is possible. That's what I thought! I have my heart set on the 428CJ, and since I have a 360 block just sitting around, I figured "why not?" Thankyou. |
| | On rare occasion it can be done properly. -- Dave Shoe, 09/30/2001
Anyone can bore a 360/390 block out to 428 dimensions, but if you collapse a paper thin cylinder, don't blame Ford.
The 360/390 block is absolutely different from the 428 casting. The 428 welded "A" casting can generally be bored to 4.160" (+.030) and the 428 welded "C" casting can sometimes be bored to 4.190" (+.060), core shift permitting
360/390 blocks can generally be bored to 4.110" (+.060), core shift permitting, but taking them to .080" is just making a thin wall thinner. The cylinder jackets are NOT cast the same as 428 blocks, so why pretend that they are? You can either build a durable 390 from a 360/390 block, or you can build a delicate 428 engine which needs a 2V intake and avoidance of high revs to keep it alive.
Only a sonic mapping of the block will tell you whether you can bore a 360/390 block more than +.030". I've got a couple 360/390 standard bore blocks that cannot handle even a +.030" overbore without weakening themselves beyond any kind of performance use. Only offset boring will allow these blocks to see mild performance use.
The 361/391 FT heavy truck block is generally a good candidate for heavy overboring. You can find these in Ford series 600-800 trucks from 1964-78. Also, some lighter trucks sometimes got these blocks, but not very often. More often, you might find an F500-series truck block with some FT features, but not with the heavy cylinder walls of the FT. The genuine 361/391FT block can frequently be converted into a 428CJ equivalent block.
Be careful about rushing to convert a 360/390 block to a 428. Most of those magazine writers who claim the .080" overbore is so desirable have never built an FE first hand. Most of those writers are full of crap.

| | | Re: c4tz-12367-a -- Mike McQuesten, 09/30/2001
One thing that needs to be mentioned when recommending the use of a 391/361 FT block for automotive use is the need for the distributor shaft bushing, Ford part # C4TZ-12367-A. I was able to still get one of these at a local Ford dealer last year. May be obsolete now. Which will offer an opportunity in the after market. An FE distributor will not work in an FT block without this or some kind of bushing.
I'm in the process of preparing an FT block at this time for future use. It's a C6ME block cast in January, 1967. It even has the 428 visable with good light in the middle core plug hole. It has the large main webbing and cross bolt bosses. So it became the perfect candidate for the spare set of 427 main caps I'd had on the shelf. Had it sonic tested and it has plenty of meat for a .030 overbore 428. It was a originally a 391. Our local 427 cammer Bonneville builder, Dick Flynn, is doing the machine work right now to add the cross bolted mains. Should provide me a strong FE block for a lot less money than I'd have to shell out for another 427 block. |
| | | RE: On rare occasion it can be done properly. -- MustangRacer'67, 09/30/2001
Well, I have talked to a person who has done this many times, and also owns an original 428CJ. He says he experiences no problems with the engine at all. If the block is sonic checked, and can handle the over boring, then what is the problem? Why won't it be able to "rev high" or handle a 4v intake? |
| | | What do you recommend sir? 390? 410? -- MustangRacer'67, 10/01/2001
Point taken. Okay, if I can't build the 428CJ out of a 360 block, what would you recommend I build? How can I get the most power out of this block safely? Go 390? Throw in the 428 crank and go 410? Since I'm building the engine from the ground up, I want to do it right. Thanks for the help. |
| | | | Study cylinder wall requirements for race engines. -- Dave Shoe, 10/01/2001
I don't mean going to school to study, I mean you should check around and learn the critical importance of healthy cylinder walls.
Thin walls do conduct excessive heat to the coolant (reducing power and causing overheating and the need for larger radiators, etc) and the cylinders do shatter more easily than properly-bored cylinders, however, cylinders also transmit headbolt torque through the block to ruggedly connect the cranksaddles to the head and they also help clamp the head gasket by adding rigidity to the block. Additionally, thin cylinders flex during use, increasing operating friction and preventing proper ring sealing.
It's easy to build a wimpy FE (or any engine) by boring without regards to the design of cylinder cores. I've read (and commented on) magazine stories where the dippy writers bored out a 390 block to make a 428 engine without sonic checking the block to see if it was cast with the heavy cylinder walls (it wasn't a heavy-wall type of block). While looking at the cylinder deck these knotheads said, "look at all the meat between those cylinders (of the 390 block). We would take it out to the biger 427 bore, but we don't want to pay extra for the pistons". Not only did they build a wafer-thin 428 engine (and write about it in Car Craft mag, July99), but they suggested they were willing to bore until they hit water, except they couldn't afford pistons. They insulted the FE many times during the article (e.g.: "This engine will never see the high side of 5000 RPM, etc), so why would any FE engine builder want to take their advice. Sadly, a rash of "bore and stroke to 428" articles came out about then, some sorta "follow the leader" thing, I guess.
Many folk have commented in these forums on cylinder characteristics and FE engines. You might try the search feature and look for such words as "sonic" or "jacket"or "core" as a starter.
If you seek another analogy which more obviously paints a picture of what is going on, you might think about simply offset-grinding a 390 nodular crank to the 410/428 specification. while the crank may still be quite sturdy, the rod journals will be visually thinner and the more flexible crank now has a lower resonance frequency, so damping becomes more important. Chevy engines may have smaller rod journals, but Chevy engines were designed for forged crankshafts, which allow this. FE journals were designed for nodular crankshafts. Other issues become factors, such as the drilled oil passages will occasionally break through where the journal was turned down, causing oil to leak.
If you do end up turning a 390 into a 428, you might just find yourself with a thinner wallet, a broken engine, and a hankering to start playing with Chevy crate motors. On the other hand, if you have a heavy-cylindered 361/391 block, you might do O.K. with it (only a sonic map will tell you in advance).

Shoe, what's your experience WRT the original applications for 428 "A' castings and 428 "C" castings? I've confirmed numerous "C" castings as 428 CJs, but every so often I hear people talking about the "A" castings as either 428 PIs or 428 SCJs. |
| | | | I've got a great looking "A" block. -- Dave Shoe, 10/01/2001
I took the "never disassembled" 428plain motor out of my Q-code 1967 LTD. It had the original valve cover gaskets and exhaust manifold "heat deflector" gaskets, so I know it was all original.
I sonic mapped the 428plain "A" block and the core shift looked excellent. I mathematically averaged the cylinder jacket diameter of all eight cylinders, comparing it to an FT block I had sonic mapped at the same time, and the "A" block had cylinder "water jacket" diameter numbers which were about .030" less than the 361/391FT block.
Based on this info, I'd be happy to take the 428 "A" block out +.030" and run it hard, but I'd be happy to take the 361/391FT block out to 428+.060" and run it just as hard (Note also the FT has reinforced cranksaddles, but the 428plain "A" block has standard cranksaddles).
Basically, the stock-bore 428 "A" block has cylinder walls which are exactly as thick as my plain 360/390 blocks. This means the 428 "A" cylinder jacket has a diameter about .080" larger than the 360/390 plain block. Basically, the 428 "A" block is exactly as sturdy as a 390plain block, but has enlarged cylinders - go figure.
I've never sonic mapped a 428CJ "C" block, but I suspect it uses 361/391FT cylinder jacket dimensions. I suspect these dimensions are .030" larger than the 428plain "A" block jackets.
As for 428SCJ engines getting "A" blocks, I sorta doubt it. Earlier 428PI and early 428CJ engines were rumored to have gotten the "A" blocks when supplies of the "C" block were low for some reason in 1968, but I've seen little indication this carried over into the 1969 model year, in particular to the 428SCJ block, which was designed to stress every component it had. I believe all 1969 428 blocks got the "C" block. Casting of the "A" block would have been fully phased out in 1968-1/2 when the midyear Galaxie XL dropped the 428plain engine as an option. Logically, only 428 "C" blocks would have been commissioned by the foundry from late-1968-on.

| Shoe- about those oil pans.... -- mikeb, 09/28/2001
My Fairlane Cobra was built October 6, 1968. I had thought about getting a performance oil pan anyway, but now you got me worried about the years itdidn't have one. So the stock pan with 5qts is not sufficient for protection purposes? scary thought. So until I do get one, should I use 6 qts in it? Generally, I occasionally got on it, never thrashed it too much thanks mikeb |
| | Yup. Just add an extra quart to the stock pan. -- Dave Shoe, 09/28/2001
Ford didn't change the pan when it recalibrated the dip stick on the CJ engines, so it seems reasonable to add a quart to any fast FE.
There might be a drawback to doing this in a non-CJ car, however. The CJ might have gotten away with the extra quart because of the windage tray. It's possible that adding an extra quart to an FE without a windage tray might cause the extra oil to whip out at high-RPMs because of the crank windage. I don't suspect this would be a serious problem, but it's possible, and it might cause unusual smoking when high-RPMs are attempted.
All just my opinion, Shoe. |
| | | RE: Yup. Just add an extra quart to the stock pan. -- mikeb, 09/28/2001
thanks, One thing that aggravates me about the CJ is all the "before this date' and after this date" that goes on with these engines. If I ever have serious engine problems I won't have a clue as to the right parts to use Mikeb |

| 428 scj -- PETE SINCOCK, 09/27/2001
Finally found one! It's a totally stock 428 scj out of a wrecked "69" mach 1. An old lady down the street has had the mach 1 sitting in her garage since "74"(her son died in the accident) The car was rear ended and the trunk is now in the back seat. The engine appears to be ok!? I picked up the car for $500. I will be putting this engine in a 69 cougar xr7 4 speed car(391 traction lok). I want to warm this baby up a bit, so i will be doing a total rebuild and I was thinking of the Edlebrock FE heads and intake. My reason for going with after market heads and intake is the weight savings. What other things should I be considering in this build up? I still want this car to be very streetable. Should I use the orginal 735 cfm carb? ETC.ETC.
Thank you for time,
Pete |
| | RE: 428 scj -- Gerry Proctor, 09/28/2001
Pete, Using the Edelbrock heads won't substantially improve your airflow over the CJ heads. They also won't save you a huge amount of weight either. The biggest weight savings is in the intake swap.
Just my opinion here, but spending $1,200 bucks for cylinder heads to save 30 pounds without a big horsepower increase is not good bang for the buck.
Keep the 735cfm carb, consider using headers, and look at some of today's cams. The stock SCJ cam is a fairly tame stick. You can really punch-up the mid and top-range without giving up the bottom end with a little more lift and duration with wider lobe displacement angle.
Also, do whatever you have to do to retain the oil cooler. |
| | | Replace the oil pan. -- Dave Shoe, 09/28/2001
Lotsa folk do "oil mods" to their FEs because all the books tell them how crummy the stock oiling system is.
I tend to disagree with most of the mods, in particular since most of the instructions leave out the only crucial problem I can see: The oil pan.
A car running 15 second ETs in the quarter can generally get away with a stock oil pan with no problems. This includes many 390GT cars. Early 428CJs got this same oil pan, but apparently accelerated fast enough to drain the pan dry during a race, so in the early 1969 model year Ford recalibrated the 428CJ dipstick to show "full" at six quarts. Two weekends ago I witnessed an early 1969 Mustang 428CJ car with SCJ gears lunch it's motor. The driver had run 180+ passes on the motor with no problems, but still had the early dipstick in the car. This day was the first time he ever raced without "overfilling" the engine with a sixth quart. He'd simply fogotten to add the extra quart and did not realize it was all that importany. On the third pass he spun some beaings in the traps, after running two passes which were a little slower than usual.
If you run in the 14 second e.t. bracket, the extra quart is a marginal fix which will help your engine live longer, just as long as you don't run a performance pump that will drain your pan even faster.
Since you will be moving into the 13 second bracket or better, I'd strongly consider a baffled "T" pan of some sort as the number one, and possibly the only oiling modification for this engine. Other mods, such as adding restrictors to the rockershaft feed line and 1966-earlier style rockershaft drip trays (with the drainback channels stamped in) to prevent excessive oil puddling in the heads, or a performance oil pump (available in HV, HP, and HVHP varieties) with the requisite reinforced pump driveshaft, etc, are all good ideas, too, if done in the proper context.
Headers will obviously wake the engine up, as would a modern camshaft kit. Be certain you select headers which are compatible with 427/428CJ/pre1966/C6AE-R/Edelbrock heads, not the emissions-type heads which have a confusingly different exhaust port location.

| | | | RE: Replace the oil pan. -- Travis Miller, 10/01/2001
A good way that a stock oil pan can be improved is to weld in a oneway flapper door made out of piano hinge. Position the piano hinge at the rear upper edge of the deep section of the pan. This will keep oil from being thrown to the rear under acceleration but will allow oil to return back to the oil pump pickup with no problem. |

| | | | RE: Strong engine? -- Mike McQuesten, 09/27/2001
My concern about advising someone to go with the Performer RPM package is that it may not work as expected. It's my opinion that to get the benefits of the RPM deal, you need to do some serious head work especially on '69 390 GT heads. I like the header idea, those stock ex. manifolds are so restrictive. How about the stock '66-'68 GT/CJ cam? I know I sound like a stuck record on that shaft but it's a good one for a mild street FE. Crane & Comp can provide it. Even E-brock's regular Performer cam might be as good a choice. Definitley run an aluminum intake, like the E-brock Performer. Maybe slip in some 3.89 rear gears. They work great for all around driving with an automatic. Maybe not for a big road trip but I lived with them and a C6 for occasional 200-300 mile drives. Better ignition, i.e., MSD or Petronix ignitor would be nice with a recurved distributor. Stick with 600-700 CFM on the carb. Just quick thoughts. The '69 390 GT was a real dog. Ford took a step back with the cam. |
| | First off, it's not a 390GT engine. -- Dave Shoe, 09/27/2001
It's a 390IP engine. This engine lacks the cam of the GT engine.
You will really wake this engine up with FPA headers for a 390GT Fairlane (Yup, even FPA mislabels their headers a little), a nice camshaft kit, an intake manifold, and an oil pan.
The smartest intake manifold to use would be the Edelbrock Performer RPM. It's nearly perfect for this application. A cooler-looking intake would be a C7AE-F 4228PI aluminum intake, thoug these are not always in the best shape nowadays. A 428CJ iron intake is the cheapest way to make the power you want, but the extra weight is better suited to trucks or Galaxies which are heavier vehicles to begin with. Other neat options include the older Edelbrock F427 intake. One thing for sure is if you keep the stock S-marked intake, it's gonna eat up some power.
Specing a cam is over my head. I can pick my own, and they work well for me, but I don't know WHY they work well. Obviously, when replacing a cam, you MUST toss out the used lifters, and you'll probably have to replace the springs and retainers. A new-technology cam requires you to install rockershaft end-support stands, lest you bust the crap outta your old rockershaft. Since you're into the engine this far, you might as well install some CJ-sized valves to those C8AE-H heads.
Toss a 3.50:1 rear with some sorta traction-type differential (avoid the older Equa-Lock, look at Traction-Lok or maybe the hairy Detriot Locker as the way to go) in there and some sticky street tires and you'll be in the high 13 second bracket.
Since you're bumping the horsepower, and no doubt bumping the RPM range you'll be running this engine at, you really need to take the engine down to the bones and inspect everything. If the bearings and journals look good and measure out OK, then you can optionally reuse them. Note that you should NOT replace the rod bearings unless you verify the rod "big end" meets the roundness specification. New rod bearings installed in a stretched-out rod guarantees a spun bearing sooner or later - usually sooner.
Lastly, a performance oil pan is REQUIRED on all 13-second FE cars, as the stock front sump pan is guaranteed to run dry at the worst of times (for example: In the traps at the end of the quarter). A healthy 14-second FE can oftentimes live with just a sixth quart in the oil pan, and a 15-second FE can live OK with the stock 5-quarts (assuming a HP pump isn't installed and oversucking the pan dry).
Hey, you've got a great engine at the core of that car. It doesn't take much to make it outrun a stock 428CJ.

Go with the RPM Performer. It's a nice manifold and a hell of a lot lighter. The stock manifold weighs 75 pounds. You can pick the Edlbrook manifold in the box with one hand with no problems. You can also lose some valve train drag by getting some crane roller rocker arms. To keep traction, get some traction bars. LOST THE STOCK EXHAUST MANIFOLDS. You can get a nice set of headers for $250 at this one site and go with 2.75 to 3" X pipes. You can find a set of universal set of X pipes in Summits catalog You'll need to get a summit catalog. It's free and has a nice center fold every monthy. When it comes to exhaust run 1" for every 100 HP. Your 390 should make 275 - 310 HP.

It is equipped as follows: 390 IP Cobrajet intake Crane blueprint series (copy of 390gt cam) stock ex manifolds (yes the puny unibody ones) 2 1/2 exhaust pipes no headwork done 735cfm Holley c-6 3.89 gears For reference, my 66GTA convert has run a best of 14.8. It is equipped as follows: Totally stock 390gt engine with the "S"ick intake 600cfm Holley 2 1/4 exhaust pipes c-6 3.50 gears as you can see big gains are made in intake and gears compared to the 69. Now I will go to bat for the 390. I often hear what a dog the 390 is. I ask compared to what? 440's 428's 455's yeah, those are pretty powerful motors, in a class by themselves no doubt. But what about mid size engines 396, 400,383 etc. I am now looking at a Car and Driver magazine, printed in March 1966 were they had a shootout of 442 - 350hp 4 sp - 14.59 et, 396-60hp 4sp - 14.66 et, Royal GTO - 360hp 4 sp, - 14.05 et, GS400 - 340hp - auto -14.92 et, FairlaneGTA -335hp - auto -14.26 et, and a Comet 390GT -335hp 4sp -13.98et. Not too shabby for a couple of dogs, and yes the magazine did not like the 390's either, but there it is.
One more magazine did a mid -size engine shootout recently, Musclecar Review May 2000. The shootout comprised a 68 442 - 15.33, et 70 396 Chevelle - 14.99, 68 GS400 - 14.92 et, 69 Torino 390 - 14.51 et, 70 GTO 400 - 14.44 et, 73 Javelin 401 - 14.17 et, and a 69 Coronet 383 - 15.48 et. Again, I think the 390 did well, certainly not a dog. I am no big fan of magazine tests, but I think the shootout in Musclecar Review is fairl assesment of what the the average owner/enthusiast, car can do, not by manufacturers who will fudge things for increased sales. The only reason I bring these things up is because a lot of my friends as well as myself actually run these kind of cars at the strip, and I never felt the 390 does that bad at the strip and neither did they. Well time to get off the soapbox... Thanks to everyone for letting me indulge myself, and if it was too long - I apologize in advance. |

| | | | | | Ahhh...1966, of course. -- Dave Shoe, 09/28/2001
Dunno where my head was at. Musta been in Mustangland. Of course the 1966 GTA existed, it got the "unique for 1966" style of 390 exhaust manifolds.
Yeah, the strong pure stock 428SCJ Mustangs tended to hang around the 13.6 area while the 429SCJ Torinos hung around the 14.0 area. I wonder if a pure stock 429SCJ Mustang might dip into the 13s a bit?
As for "bad talking" the 390 GT style exhaust manifold, I gotta take lotsa the blame for instigating that talk. Hell, I start lots of bad rumors around here. While them GT manifolds still suck in my book (due to a traumatizing experience I had, no doubt), they can apparently post some good numbers when all is dialed in just right. This is refreshing to learn.
As for the 180 runs, I dunno, that just doesn't seem like very much. It's sorta equivalent to two months of driving back and forth between work and home for me. I'm all for rebuilding a hot motor every year or two (depending how hot and how driven), so if those runs fell outside the two year envelope, then I suppose problems would become more of a real possibility. Still, it really seemed like the death of that particular rebuild was a direct result of using compressed air to lubricate a crankshaft. Sadly, toward the end of the weekend the 428CJ Mustang owner was looking to replace the noisy rods with Eagles. Man, I hate seeing the stock rods get a bad rap just because they need oil to operate properly. Stock rods did good in that car, oil pan did bad.
As for the "young whippersnapper" observation, I can appreciate it. I was rebuilding FEs when that souped-up '69 was rolling down the production line. I wasn't any good at it back then, but I still had fun. Also, I agree the Pure Stock show was really fun - I met lotsa cool people and took lotsa cool photos. I'm especially glad it went on despite the horrible events of the week. Features like the "moment of silence" and the National Anthem took on a fresh new meaning.

| | | Beware of headers! -- Dave Shoe, 09/28/2001
Not all headers which fit your car will fit your engine.
Be sure to get headers which do NOT work work with 427 or CJ heads. Your 390 heads have the exhaust runner repositioned to the "emissions head" position. These heads are really well designed, but require headers which have the "low positioned" header flange. I'm not talking bolt holes here, I'm takling about port flow. Sadly, there are no books which explain this, and header manufacturers aren't talking, so you just need to pay attention that your headers actually MATCH the heads - lest the weld bead on the header not properly crush the gasket and thus permit exhaust leaks eternal.
