I did some mild clean up of the ports and bowl area, DID NOT EVEN MILL THE HEADS for more compression. Used the honker cai intake/ slp 85 mass ,ported stock throttle body, unported fast 92mm intake comps 238/242 cam cooks lng tubes/ B&B cat back ( loud as hell ) and a tune that holds 12.7 air/fuel at wot, was making 473/413, retuned it, removed damaged high flow cats, new ls-7 clutch/alumflywheel and made the higher numbers.

Yeah" i'll try porting the fast 92mm intake next. I was surprised at the numbers too. But i've seen other cars c6 ls2 with the same mods making 450RWHP to 460 RWHP with/out the fast intake or the patriot heads.
