I am going to be running a 3500 in my currently 3400 swapped Fiero and I need clarification regarding the exhuast manifolds.
The 3500 is out of a g6 and I am not planning on using the dual manifolds that came with it, I simply do not want to redesign my exhaust (or is this worthwhile?
Anyway, I have been looking at using manifold with a crossover like the 3500 equipped vans came with. I looked some up on car-part and 3400 manifolds keep on popping up, are they exactly the same or will I have to do some porting to match them up to the heads? Do they flow the same as the simial (or is it same?) 3500 manifold?
