| Heads, good or bad -- carlos, 03/30/2003
I have a 67 with a 390 motor, the heads on this motor have a casting number of C7AE-A. I have been told by some that these are 428 heads, are they and if the are not, are they good or bad heads to use? |
| | Fine -- Royce Peterson, 03/30/2003
Ford used the same heads on almost all FE's except the 427 in any given year. In the case of C7AE-A heads this is true also.
They were used on all standard FE's in 1967 such as 352 (pickup truck) 390, 410 and 428. They were common on 390GT and the 1967 Shelby 428 also.
They are nothing special, valve sizes are 2.02 / 1.55. The intake ports are a good starting point for porting. The exhaust ports are low and small, some porting to raise the exhaust port does wonders if combined with larger valves and a set of headers.

| 390 C4AE Which gasket? -- Darren, 03/29/2003
What is the best gasket for these heads? I am adding Edelbrock Performer RPM Intake, Holley 750 Carb & FPA Headers. Thanks! |

| | RE: 390 C4AE Which gasket? -- Justin, 04/09/2003
I'm running the same heads and intake and use fel-pro #1020 and for my headers I use fel-pro #1442. You can get them at any auto parts store. |
| 390 fan shroud -- Ed McManus, 03/28/2003
Would anyone have an idea if this fan shroud should fit my '67 Fairlane(390, C-6). Part # C6AE-8146-A. Thanks, Ed |
| Intake -- John, 03/28/2003
I need some help deciphering the following casting number...C3AE-9425-K Its a 2X4 Aluminum MR intake(I'm assuming MR since it does fit CJ and 427MR heads) The killer is the K. I have looked at all my Ford FE engine books and material and could not come up with a match. Could it be a special production?? Any help would be greatly appreciated....Thanks in advance...John P.S. Whats also interesting about the K is that it is stamped in opposed to being a cast number. I checked with a magnifing glass and no number was ground off underneath it...the cast numbers actually stopped after the 5 then a dash and the K was then stamped on. |

| | | RE: Should be a 427 LR 8v intake. [n/m] -- John, 03/28/2003
So do you think the K may represent a design or spec. change? The reason I ask is according to my FE book, J was the normal letter used in the casting number for 427 2X4 LR intake. There is no listing of K in any of my info. or books. Thanks Again....John |

| FPA headers Vs. Hooker super comps -- Mike, 03/26/2003
I am in the market for some headers for my 69 428 mach 1. I am wanting some opinions on which header to go with. I have heard the FPA's can be installed on the engine then put the motor in the car which is a bonus. I have heard the comps are a pita to install. The FPA's are a 100's more for coated headers than coated hookers. The hookers look like they would be a better design for more HP. I do like the fact that FPA's are built on the car maybe hooker does that too. I guess what i am asking is does anyone have anything to say about either brand to sway me a certain way. |
| | RE: FPA headers Vs. Hooker super comps -- salid, 03/26/2003
If you are after the absolute highest hp you can get, you probably want the Hookers. But you really need to ask yourself two questions. 1. How much more power will I really get? and 2. Do I really want to turn my 34 year old engine above 5700 rpm to get that power? I used to show folks how fast my car (68 Shelby 500KR) would go and run it till the valves started to float at about 6800 rpm (about 150 to 155 mph, I think). It would do it with no hesitation (with Hookers), but it turns out that it's not a very good idea. I don't really think you will be able to tell the difference between the two headers up to 5500 rpm, except that the FPAs will give better torque at low to mid rpm range. One more question you might want to ask yourself is "What do I plan to do with this car?" If I was building a drag car, I would go with the Hookers, get a cam, valve train, intake and headers and lower weight rotating parts (probably with a new crank) that would let me comfortably wind to 6500 rpm and a drive train and suspension that would let me hook it to the ground. Man that sounds like fun. If I'm building a street car, I'll use the FPAs with more modest improvements in the breathing area. I'll get plenty of power without having to upgrade all the other pieces. I took my car up to Spokane and ran on the track up there last summer. My brother-in-law rented the track, so 8 of us had the track to ourselves. I promised myself that I would not wind it higher than 5500 rpm (about 130 mph, that's actually pretty fast), and I pretty much kept to that limit. It will go to 5500 rpm with no hesitation at all. I have had both headers on this car. When I detailed my engine compartment, I took off the Hookers and went back to the cast iron, cuz I thought I wanted it to look stock. When I compared the Grin-o-meter results as I looked at the cast iron manifolds to the Grin-o-meter results as I accelerated using headers, I decided it was time to go back to headers. For those of you who have never used a Grin-o-meter, it is a highly technical device that explains why we suddenly reach for our wallets when looking at a new set of headers or why in extreme cases when we look at something we REALLY need, we tend to begin to droll and the dollar bills begin to fly out of our pockets. I do not regret choosing the FPAs at all, I'm really happy with them. |
| | RE: FPA headers Vs. Hooker super comps -- Brian Crisman, 03/29/2003
Just to clarify a little. I installed the FPA's on my 390 into a 67 Cougar and you cant bolt them up to the engine on a stand then drop the engine right in. You can lower the engine about 2/3's then bolt the headers up.....which you may be able to do with the Hookers also but I don't know (I've never tried it). I really don't have anything to offer to sway your opinion. I have the FPA's, they fit great, my engine has plenty of power, it sounds great and I would buy them again. |
| | | RE: FPA headers Vs. Hooker super comps -- Dave, 04/04/2003
I put the FPA tri-ys on my 67 428, and we were able to drop them into the freshly painted engine bay without a nick. No tranny on. Put that on from underneath later. |
| | RE: FPA headers Vs. Hooker super comps -- Ian D.., 04/13/2003
I have Hooker Super comps on my 69 FB and they are not at all speedbump friendly.
I'm building an new motor to put in in and when it goes in it'll be with FPA's instead of the Hookers, I'd imagine that they flow pretty much the same with the bottom tubes flattened out like they are now :( |
| | | RE: FPA headers Vs. Hooker super comps -- Geoff McNew, 04/30/2003
What is all this header nonsense I keep reading, Hookers or tri-Y's? Hooker SuperComps will mount to the engine, all 32 capscrews, and install in-place without hitting anything in the engine compartment of a 'stang....I just did it today on my 428-SCJ in my '69 Mach. My wife watched out for the firewall and although a beer buddy was on hand, no extra hands were needed. HERE'S THE KEY: buy a TD engine tilter....best damn $64.95 I ever spent - it takes all the grunt and b.s. out of positioning the engine.
As for flattening out the bottom tubes, do what I did - put in some 600 LB coils and watch for speed bumps. The Hookers will outperform anyone's "tubular manifold".
p.s. put Stage8 header bolts & locks on, or be sorry. |
| FE Heads -- jesse, 03/25/2003
I am wanting to find out what these heads are the casting number on them is 6090-c/edc and that is all that is on them and they are not 427 heads of any sort. but they do have machined combustion chambers and the valve spacing to fit a FE small as a 352. |
| '66 door skin -- alexander, 03/24/2003
I was wondering how hard it would be to change the door skins on my '66 coupe, also if anyone has any recomendations or complaints about specific companies regarding this sort of part, I saw some for sale on e-bay($40 ea) but I haven't looked around to much, thank you for your time |
| | RE: '66 door skin -- Lou, 03/24/2003
Talk to a body man, this is not a easy job but it can be done. Might be worth taking the doors off and bringing them to a shop and have them shin them. |
| 390 baffle plate under intake (reverse 105) -- Michael White, 03/24/2003
Do all 390 FE big blocks use a baffle plate under the intake manifold? I have a 'reverse 105' engine on a stand and there is not a baffle plate under the intake. Would it be a mistake to rebuild this 4v FE 390 engine without using a baffle plate? This engine was partially disassembled when I bought it and I don't know if it ever had a baffle plate.
Can anyone provide info about the reverse 105 FE big block? I've heard that the cylinders are thicker than a normal block and the main bearing saddles are reinforced with additional ribs. Is this true? |
| | A 105 block is just a later casting. -- Dave Shoe, 03/24/2003
The rumor that 105 blocks have thicker cylinders is wrong. The 105 was simply the symbol the Michigan Casting Center (MCC) used whenever it cast an FE or FT block. MCC first came on line in 1971 casting steel ingots for Ford's steel plant and started casting iron parts about a year later.
Most all 105 blocks did get the extra cranksaddle webbing, but only a minority of them came with thicker "FT" style cylinders.
Note that most, but not all, 361 and 391 FT engines got thicker cylinders than the 360 and 390 pickup motor. Some 360/390 blocks got thicker cylinders, but they are really not all that common.
You can tell which type of block you've got by popping out all six core plugs and using the shank of a 15/64" drill bit. Reaching into all six holes and probing all reachable areas in the block, if the drill bit fails to slip between the cylinders in at least one spot on the block, then it's likely a thick cylinder block. If it does slip through in at least one spot, then it's likely a standard cylinder block.
There is some random variation which will sometimes make the drill bit test give improper results, but it's pretty darned good for the cost of a drill bit. Actually, carrying 14/64", 15/64", and 16/64" drill bits (I only speak in 64ths to avoid translation mistakes) to a salvageyard or swap meet will help give you a better idea what you are dealing with.
Note also that you can sometimes get away with testing inside just one core plug hole, but it's important to realize that the chance for errors increases if all holes are not completely checked.
Also note that this test does NOT check for core shift, so it's possible the jackets and cylinder cores were improperly aligned, making thin spots along a cylinder wall. A sonic map will be needed to sort out exactly what you've got. The drill bit test is simply a cheap pre-screen to help put the odds in the buyer's favor.
The baffle is needed on all FEs that have an active exhaust gas crossover between the heads, as oil can burn to the bottom of the intake, either degrading the oil faster than normal or else creating charcol bricks in the galley.
Note also that Ford no longer made the FE and FT engine from 1973. Production was moved to Clifford Manufacturing, in Clifford, MI, and Clifford determined who would cast the parts. It appears MCC was the main foundry.
It also appears that DIF remained involved with casting industrial FE goodies after truck engine production moved to Clifford. Kinda a strange twist, but I'm still learning these odd details.

| | | Sometimes you learn two somethings new every day. -- cuzncletus, 06/28/2003
I had heard about the drill bit test but never had it explained to me. I also didn't know the details on the castings until I went to your old post. I already have the 105 block in my 62 Galaxie, .030 over, but am contemplating a freshening. More than cubic inches, I'ld like to get away from low dollar rebuilder cast pistons. Any ideas besides the Ross'? |
| | | | It's tough to beat the cheap Ross pistons on ebay. -- Dave Shoe, 06/29/2003
TRW and Sealed Power pistons tend to be cheaper and heavier (same as cast weight pistons), and are great for builds that are not goind to hit ultrasonic RPMs.
Ross pistons can be bought CHEAP by one reputable seller on ebay and these lightweight pistons are suitable for higher RPMs. The reduced mass of the pistons means you do NOT want to supercharge them with nitrous if you seek longevity.

Shoe, Which blocks got the larger bore distributor, was it just 361/391 FT's? |
| | | | I believe... -- Dave Shoe, 07/06/2003
...the 330HD, 361, 391, and FT service blocks got the large distributor pilot hole. The 330MD may have also gotten the larger pilot bore and been bushed to FE pilot size, but I forget.
The bushing to convert an FT pilot hole to FE pilot size is still available at your Ford truck dealer for around $22.00 or so. They are fresh new stock.

That baffle you mentioned is to keep oil off the croossover passage in the intake maifold. My experience is that you will smoke alot inside the engine if it left out. Put it in I think is best. |
