Looks a little over kill on the compression. I run 11:1 on pump gas with a cam and heads like that. A little racing fuel might be a good idea.

The carb seems a little small but the intake should help that.

What kind of transmission are you going to use???? Is that the Fiero trans?

I assume that you are not going to run pump gas. If that is the case, and you are already going to be running race fuel, why not make it 13-14:1? Also, if this is a race car, I would run a little bigger cam and a 750 carb. This motor should make power to 6500 RPM pretty easily, I think that would warrent a 750 but I could be wrong.

Actually, I looked at that cam you are looking at, and I think it will work well.

Your trani and cv's will not hold the power... lol.. Maybe for a little while. But launching the car will make it worse. I suggest NOT doing hard launches on the car.

I am not familiar with fiero trani's and cv's, but I dont think it will hold.. I could be wrong, but I doubt pontiac built them to hold 400+tq...

You might have to go with a 930 trani box, or such.

Anyways, good luck! Mid engines with big tq are a lot of fun!!

looks very unique. did you mill the brackets up yourself? i guess with right tools you can do anything. good job guys! i know a couple people who attempt to do swaps. competent wrenches, and they sank $ in, till they had to sell. the same time they were telling me to put a v8 in my toyota truck. i have mad respect for you, and the love for which you express on the car.

I agree, that setup looks very nice. Really clean. Most of the v8 swaps I have seen are hack jobs with random wires laying everwhere. That should be alot of fun.

Fierro's and torque...

My buddy Mike (works at the garage with me) has a 383 with a blown tranny in a fierro. Its a pretty tame build too- don't launch the car hard untill you get the drivetrain beefed up everywhere. Also, the compression is a bit high- I'd go with 11:1 for the street (as previously mentioned)- I assume its for the street. that thing will be wicked when its done.


Look at eh Opel Speedsters- they're like the Fierro, but modern and with ECOtec, yea its a 4 cyl, but still a cool car. Dam Aussies...
