An exact duplicate of the cast iron 428 Cobra Jet manifold, which is an entirely different casting from other run of the mill FE intakes.

Yes its true.

If you put these two manifolds side by side, you will see there are minor differences between the two but close enough for government work. The CJ is not an exact copy as everybody says, the runners are a tad bit narrower and the carburetor flange and plenum are different but it still takes a Holley. Bill Carroll’s Fooorrd V8 Performance Guide says the PI manifold is good for 11 more horsepower. When I put one on my CJ, I noticed an increase in power above 5000 RPM but also noticed a slight drop in bottom end torque.

Ron. WEC-K- 3.00 comes up as...
69 comet or 69 to 71 fairlane or montego
3.00 ratio-39 ring gear teeth, 13 pinion teeth,
9" ring gear, non locking (open), 28 spline axles.
9BB is a date code. 857A I believe is a plant code.
Hope this helps.

Here's are three sites that will help,

What pistons are you referring to? Are they stock pistons? Check out Speed-Pro's (formerly TRW) L2291F piston, I believe that it yields about 9.5:1 with most heads but don't remember for sure. The compression height for these is 1.776. Stock pistons were cast according to Steve Christ. You can also get cast pistons from TRW, part no. 381P I believe. Not sure on the comp ratio for the cast pistons.

Probably not, But in the movie it was protrayed as a 427. As most 427s they are rare and kick @ engines in what ever body they were installed. This was a lengthly decussion after the movie came out. Some say it was a SB. Maybe someone with the facts will respond. Nobody seemed to know back then.

There was a good article in a mag shortly after the movie came out. There were several cars - something like 12-13. Most had small blocks. One was an original 390, but I don't know if they kept that engine. One was hopped up a lot and either driven or kept by a producer or other big-wig. That may be the one you're thinking about. None of them were real Shelby's except for the one used in the very last scene. That's the scene where Nic Cage's brother gives him a car.

I don't remember all the details, so I may be off a bit. I may have the article in the garage. If I find it I'll post.

I thought I read somewhere that most of the cars used in the movie were Windsors, not sure though.

I figured the cars they used for the jumps and stunt driving had windsors, and maybe the show car had a real 427. I was watching a show on movie cars on some cable channel last week and they showed Elanore , but I never heard them say what engine THAT particular car had in it.

ok here goes. i dont know this first hand but i try and read everything a i can posibly find on old fords and especially FE's. there was a article in mustangs and fast fords about it. there were several cars. none with a 427. there was different cars for different stunts. jumps, chase sceans and so on. from what the article says. there was only one real shelby that never seen the silver screen. that car happended to be a sheby with a 427 s. oiler. from what i understand he moded it after the movie to look like it. also not to hurt anyones feeling most of the cars where 351 crate engines, which would make sense. i do in fact have the article. so ill try and scan it tomarrow. ill try and have it up befor the end of the week. someone email me and remind me. cause im at work right now.
oh ya the only car that had an FE in it was the clunker in the end.

A hydraulic roller should be fine, but if you want to go solid, there's a concern that the roller will scuff the cam. I don't know if it'll actually happen, but that's what I've heard. A rev-kit should fix this, but I don't even know if it's a problem. Oh yeah, the concern is for street-driven cars, not strip.

I tested some roller cams in dyno2000 and they seemed to pull about the same as my normal solid cam until about 4,500 rpm's. The roller past the solid at 4,500 and kept going up where it made about 50hp more than my normal solid. If I had my engine apart, I'd set it up with that cam. Dyno2000 has a feature where you can test all specs within a range. You plug in your flow-bench numbers, and it does the cam searching for you. The cam it chose is actually very close to the CompCams 288-R10. The 308 and 328 had higher numbers.

Porting the heads seemed to help about 15-20hp. So did a single plane versus a dual plane. Yeah, the dual plane had more torque earlier, but the numbers were so big, it wasn't like the engine was hurting for torque.

So, if I could do it all over, I'd port my heads, run a single plane tunnel wedge 2x4, and I'd run a custom roller - chosen after putting my heads on a flow bench.

I would recommend a roller - I have a Comp Cams 288 solid roller in a stroked 427 side oiler that runs great. Plus you don't have to get all twitchy breaking it in.

restoring 69 mach1 r-code need to assemble motor and paint and it will be done in may.Just in time for some nice weather.

I am currently trying to get my '55 F-100 together. 390 Tri-Power, C-6, 9" rear. The body may be rough, but it should run pretty well, which is the important thing anyway right? The weather in Washington has been decent lately, now if that @##$ wiring harness would get here, I could get busy.

The bore is identical at 4.13" for both the 406 & 428.
When you add a 428 crank, you are making a 428.

i did this type of fe combo a few years back, but with a little different head. if you have the stock 406 piston you need to go to a custom job & change compression height on piston, raise it about .025 to .045 depending on cc of head. this will give you less deck clearance to make up for larger cc head that you are using. 406's are about 56cc to 67cc. the head you have has 71cc to 74cc chambers. if you don't do this compression loss will be huge. so buy all means go the custom piston way. hope this helps.

Use the stock 428 piston. It is correct in every way. The C-4 head has a chamber volume of almost identical size and shape as the C-J head. If you have not had the rods or crank rebalanced, you can get away without the expense of a balance job, unless you have something else in mind.There are different ones however. The stock T-bird-Galaxie-Police car one has a deeper dish top. It will give you around 9:3:1 w/ your head and a Fel Pro #1020 gasket. The C-J and S-C-J another point higher. The Super is stronger but heavier, however you can reduce the weight some by grinding and the lighter pin of the C-J or T-bird.
