550 RWHP? That'd be cool. Whats the compression? Do you know what those heads flow?

I would guess north of 550rwhp in a M6 car.
Biggest bottle neck is the Fast 90 intake, get a custom sheet metal and you could gain 30hp or more.

Do they make a sheet metal intake to fit under the F-Body hoods and under the wind shield area. I can build one if i had a (picture), I made my own valve cover for this engine.

if you didnt get 550 rwhp i would be upset. that 402 with the tfs heads put down 550 and i bet they dont flow like that. with a carb style intake i would expect a gain over the fast setup. but i dont think 550 is goin to be a problem
