I bought a 1978 trans am with the 400ci pontiac engine. The engine had water in it so i decided to pull it. I found that the rotating assembly is all stock; stock cylinder bore and stock bearing sizes. Its all in very good condition. The car has been sitting for years and it has low miles. So with this in mind, I would like to save the money of buying new pistons and having the block bored. The heads im running are 110cc with 2.11 intake valves and I believe the engine ran in the low 8's for compression, im not sure though. I would like some advice on what I should run for a cam, carb, and exhaust system, rear end gears, and ingnition system for a really fast street car with out changing the heads, and maybe a suggestion of a good set of pistons that would work well with my heads. The engine already came with an edelbrock performer intake and large tube full length headers. I will be running a 4 speed tranny and a 3.23 gears for now in a posi 10 bolt rear end. Let me know if i would need a high performance clutch, or different gears, or if balancing of the rotating assembly is really needed. Some suggestions would be really helpful. Thanks.
