I would say you are going to be well into the 500 HP range being the car is a M6. That kind of HP should be doable while keeping the car very driveable. We've done several 402 c.i. motors w/ some fairly aggressive cams going 525 to the ground. W/ some more cubes, we should be able to get that kind of HP while going w/ a little smaller cam to keep it pretty driveable.

were putting the same engine in my vette now (its being freshened at the machine shop) i will lety ou know how it goes. this was extremely driveable even in my big heavy gto... so in a vette it should be an utter joke.
