| 4v cast intake -- Jack, 01/01/2005
do I have to go with a 4v stock cast intake on a 69 390 w/shaker? or can I substitude elderbrock intake and still keep same height for a repro shaker fit? Jack |
| | RE: 4v cast intake -- raycfe, 01/01/2005
Not an answer but, Some aftermarket manifolds mount the carb in a different spot, I seem to think about an inch back. Something you should check out. Ray |

| Crites headers for 1969 Mustang w/428 CJ -- Alex, 12/31/2004
Hello,
I wanted to know if anybody has had any experience with Crites headers for 1969/1970 Mustang w/FE engine. Please let me know if they fit well, leak, have ground clearance problems with speed bumps, anything you might know.
Thanks, Alex |
| | RE: Crites headers for 1969 Mustang w/428 CJ -- FPA Racing, 01/05/2005
Give me a call . If you require a (no leak) HD 16 gauge construction header for your FE Mustang with MAX ground clearance and you can actually both both headers to the engine and drop it in as a unit. Over 1000 sets sold.www.fordpowertrain.com |
| | | RE: Crites headers for 1969 Mustang w/428 CJ -- glennz, 01/05/2005
i will definetly vouch for FPA on this one,
67 fe fastback,
bolt headers on, drop engine in, 30 minute job max,
OR
set motor in then bolt headers on 3 hr job pain in the a$$
no leaks, great performance, great quality

Glenn, are you running a 4 speed? I am having trouble with the Z-bar hitting the FPA headers/ |
| | | | | RE: Crites headers for 1969 Mustang w/428 CJ -- glennz, 05/17/2005
no this is a C-6 car |
| | | | | RE:Equalizer/Z-bar interference? -- McQ, 05/18/2005
I've got a friend who installed a set of FPA on a '67 390GT with factory original 4 speed evrything. He really likes the headers but he also had interference issues with the left header and the Z or Equalizer shaft. I wonder if that issue has been dealt with?
Again though, he is very happy with the quality-performance of the FPA headers. |

Would not buy anything from Crites. I ordered a readiator for my 65 galaxie. $450 part. They sent me a radiator for a 64. The Girl on the phone argued that it was the same. It wasn't. they would not allow a return due to it being custom. Had to cut my car due to the trans cooler being mounted on the side instead of the bottom. Radiator leaked, Both Crites and Howe radiator wouldn't warranty due to it being a custom order. I didn't feel this was custom, as it was an item in their catalog. $800 later the radiator is ok. The girl was very nasty on the phone. |
| Weiand Vs Edelbrock Intakes -- Boidman Of ATL, 12/31/2004
Who makes the better performing intake.Ive always seen the edelbrock,but i have also seen a weiand and an offy intake for FE series motors.This will be on a 390 that will not be seeing dragstrip duty.I just want things to be cooler and breathe easier. |
| Aluminum Radiator Of Birds -- Boidman Of ATL, 12/31/2004
Anyone here know of someone who has switched their copper and brass radiator for an aluminum one? I am finally buying parts for my 62 that some of you hear may have heard me chat about.Its going to have a aluminum oil pan,heads,intake,headers edelbrock carb and id like to further lighten the load with a aluminum waterpump and radiator.It wont be a daily driver or stock(obviously) but when i wanna drive,it wont be at 35mph.Overheating should be at the back of my mind not the front. |

I am looking for transmission linkage rod for 67 fairlane 390 c-6 factory floor shift |
| | RE: auto transmission linkage parts -- dennie, 12/31/2004
i can get you the part number and the lenght, i think it's 18 inches, as far as finding one good luck, i used one that was close and tweaked it a little to fit.. try http://mansfieldmustang.com/Transmissionsp2.html |
| Any advantage for 2.5 or 3.0 in exhaust -- mikee likee, 12/30/2004
I have an opportunity to install either a 2.5 inch or a 3 inch exhaust system. My engine is a slightly warmed over 390 in a 70 f100. Max rpm 5500. I intend to try a crossover or xpipe, any advice hear will help. |
| | RE: Any advantage for 2.5 or 3.0 in exhaust -- Gerry Proctor, 12/31/2004
You don't need 3" exhaust at your airflow rate. Once you start approaching the 500 hp level, a 2.5" system becomes a clog in the system and a 3" system really helps.
Even if you have the room and the price for the system is the same, a 3" exhaust is substantially louder than a 2.5" system. Also, you'll pay a lot more for a 3" x-pipe than the more common 2.5 pipe. |
| any diagrams for s-tube for 67 390GT? -- Clint, 12/30/2004
does anybody know how the s-tube goes on the 390 gt motor? does it go on the intake and where at on the intake etc. Is there any diagrams out there? It looks like vaccuum lines hook up to it. but what ones and where at? any help about the s-tube would be great! thanks |
| | | RE: 'S-tube'? No such thing, for '67 390. I think you mean a PCV tube... -- Clint, 01/19/2005
Yes I mean a PCV tube just like your picture. Do you know what it goes to... intake... carb loactions etc? Any pictures of it hooked up? any info would be great! THANKS SO MUCH!! :) |
| will this work? -- Jack, 12/30/2004
or will this work good?
question 1 have a 69 390 with c8aeh heads and was wondering if this is a good option as I am just collecting parts for this motor. I have the stock rockers already and want to use the stock shafts. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7944204017&rd=1&sspagename=STRK%3AMEWA%3AIT
question 2
looking at engine specs a 69 390 engine, suppose to have 10.5 to 1 ratio but I noticed a post on this site that said c8aeh heads are stock 8:1 truck heads. is this right? so I wont get my 10.5 to 1 ratio? or are we talking about diffrent ratio's. if so I have the option to return the heads even though I bought them for 200 with rockers and stock exhaust manifolds that I intended to use, but heads need to be redone.
thanks a bunch and happy new year Jack |
| | RE: will this work? -- Gerry Proctor, 12/30/2004
First, C8AE-H heads are common, run of the mill, garden variety...FE head used on everything that was not a 428CJ or 427. That includes all cars and trucks. The piston design determined the compression ratio.
The first part of your question is more opinion. You didn't provide any background on what your intentions are but roller rockers are a somewhat poor return on investment (regardless of what the seller is using to hype these rockers..."will pick that big block up around 20HP...") unless you're running a much stiffer (like over 140lbs seat pressure) valve spring and even then it's questionable. Those rockers in particular are bottom feeders. The bare minimum I would consider as adequate would have a bronze-bushed fulcrum. The top of the line use a roller fulcrum. If you look closely, you'll see that the fulcrum is parent aluminum. It is probably hard anodized or T6 treated but that's not enough in my book.
There are more and more valve train options available for the FE builder but the key remains in making smart choices. If you're not running anti-pumpup lifters (or solids) and reving over 6k rpm, then the factory hydraulic, non-adjustable rockers will work just fine. If you need adjustables, there are iron (Crane, FRP...) that will work with stock shafts and only need the ball and cup pushrods. There are some good aluminum roller tip and roller tip and fulcrum rockers out there. There are also upgraded shafts, stands, end stands, and spacers available. It gets real easy to spend over $1,000 on the valve train. If you're going to spend the money, you want to make sure that you get a return on your investment in either durability or horsepower (getting both is even better) and these particular rockers, again, in my opinion, are neither. |
| | | what about the heads? -- Jack, 12/31/2004
i dont know if i should keep the heads. so as long as i get the right stuff i can still get my 10.5 to 1 ratio? Only reason I went with those heads is that the came with everything including manifolds for 200 bucks. I mean should I return the heads or are they still decent as long as I get them redone? Thanks Jack |
| | | | RE: Replace them with what, and why? -- Gerry Proctor, 12/31/2004
You'll get your compression with those C8AE heads. Again, those heads were used on a variety of engines including the 390GT/IP engine. They have 72 cc(nominal) chambers and you can run the numbers if you know the rest of your displaced volumes to find the true compression ratio. You'll very likely find that the factory ratio spec is a bit generous. You'll probably end up in the high nines as a true compression ratio. Though with iron heads, the tuneup gets real touchy over 9:1 on pump gas.
The heads flow just fine up to about 400 hp. The exhaust port is about .25" lower on these heads than most '66 and earlier heads which can pose some header fitment problems, depending on how you go. If you can use the manifolds that came with the heads then you're golden.
Your only other options are a set of C8OE-N Cobra Jet heads, Edelbrocks, or a set of ported heads from '65 and earlier. |
| 428 cj bellhousing -- Rudy, 12/29/2004
I am looking for a bellhousing from a 428 cj. I want it to install it on a 390 mated to a 4 speed top loader witha 1 3/8 input shaft, the original 390 bellhousing does not clear the clutch pressure plate, and I was told the 428 cj bellhousing will, any leads? I am using the 428 cj centerforce clutch assy. |
| Offenhauser intakes -- giacamo, 12/28/2004
has anyone used the offenhauser dual quad manifold #5407 for the fe? i picked up one cheap, is it worth a dam.or just interesting. |
| | RE: Offenhauser intakes -- John, 12/28/2004
I use one......you'll have to get the offset spacers (still available from Offy I think). Mine works great....more power than I can put to use. ONly thing I didn't like is the ports are tall and narrow......must have been meant for heads other than my standard FE ones. But as I said.......I can't utilize all the power I have in a 2500 lb car, though I am sure there are better drivers who could. |
| | | RE: Offenhauser intakes -- giacamo, 12/29/2004
thanks john i think a littel port maching is in order, and playing with the carbs it is a neat setup never ran duel carbs befor but am willing to try |
| | | | More on Offenhauser intakes -- John, 12/29/2004
Do a search on the dual carb set-up in this forum. I wrote at least one letter detailing it it. Basically, 1 carb does all the work till about 1/4 or maybe 1/3 throttle (I forget which) and then the other one starts to open. The belcranks are setup for both to end up open at the same time for wide open throttle. 600 cfms are good. Vacumn secondary's need to be connected between carbs for synchronous secondary operation. Primary idle circuits always run, so it will be rich at an idle unless you modify carbs, even with adj screws all the way in. Pony Carbs can do this for you, but is expensive. One of the SD Holley books explains how to do it cheaply. |
| | | | | More info.... -- John, 12/29/2004
I did a search and found some of the stuff I once wrote....hope it helps. If you have any specific questions you'd like me to look up, feel free to e-mail me for a quick response, or eventually I will see your question in this forum. Here goes:
The linkage needs to be adjusted so the second carb comes on after the first carb gets to about 1/3 open throttle. Then the second carb advances at a faster rate so that both wind up fully open together. So, you may need to modify the second carb bellcrank as the linkage pin is in the wrong spot on carbs designed for single operation. Also, a air balance tube must be added. Instead of getting new vacumn covers, you can drill and tap each existing cover for a grease fitting. Use the 90 degree ones and remove the balls and springs. Tighten and adjust till they point towards each other for a tidy vacumn hose installation.
Pressure is nice about 7 to 8 psi. However you could have a fuel pump which is inadequate (possibly) or a fuel filter which is restrictive (most likely), or even too small fuel lines anywhere from tank to carb (so the experts say, but I havn't had any trouble with lines smaller than 1/2". About those 600's though. The ONLY difference is to the idle circuit as the idle adj is for fine tuning only. Two carbs give off twice the fuel they should at idle with the mixture screws in the normal position, but will run OK, but still rich in the fully closed position. The progressive linkage neeeds to be set up correctly and make sure the carbs are monted in the right position as the belcranks are different front vs back carb. If the fuel supply turns out to be OK, sounds like your driveability is in the accel pumps or possibly the vacumn advance. Are the vacumn advance connected together for synchronous secondary operation? If you use regualr carbs, you can drill and tap and add fittings to the vacumn chamber caps and add a balance tube. As far as the accel pumps go, check the colour of the cam and make sure both are the same and the nominal type (I forget that colour, but any Holley book will tell you that) and the 50cc pumps are a better bet than the smaller ones if you use an after market HP cam. Maybe the spring rates should be changed, but this hasn't had much affect in my experience.
The problem with 2X4 Holleys is, as noted earlier in this thread, the idle circuits. Although the engine may draw the right mixture at speed, as the air fuel ratio is governed by the main venturis, the idle circuits are set with the assumption that only one carb is on the engine. Two carbs...twice the needed fuel at idle. The mixture screws are only a "fine" adjustment, so you can turn them in all the way and it's still too rich. The idle jets must be reduced in size until they are close enough to allow the mixture screws to lean out the engine to a stall. They can be replaced, or a small wire bent into a "V" with little feet bent on the ends, can be inserted in the jets. The secondary idle circuit (used to bleed off fuel in a lightly used car so it doesn't get stale) don't really require the same attention. You can fiddle around with the wires till you get it right and probably spend $900 in float bowl gaskets, or you can get someone to give you out of the box units with the correct vacumm balance covers. Pony Carbs supplied me with two units that work perfectly with my Offy 360Deg manifold (which many hold in disdain). You guys with other FE's out there might be faster, but I havn't seen a Chevy yet that was. |

thanks john your post is very informative,i even printed a copy now the fun part digging through all my carb parts to see what i can use and or need. |
