I'm planning on going with a non-stroked 351w block, crank, rods, and pistons; trick flow heads, and a stack-style EFI system. Can I hope to turn 450HP at least? Or am I looking at 400 most likely? I'd really like to hit magic 500 but I don't think I can do that without tossing out the stacks and calling turbonetics. Geeze, my head would pop trying to put on one of their systems. I'm not planning to ever race. I simply want to be confident in the face of the local z06's. Of course, even if I come up with just 350 HP on a 2800LB car, I shouldn't have any problems, hehehe.
