yeh, but look at allt he stuff he's adding to the engine, looks to me like he's taking this seriously, and a c5 with slightly higher comp pistons or a ls crank could achieve similar results... if he's shooting to do high comp and not go over 11:1 then it really is kind of pointless to go high comp... i'd say shoot for 12 and get big ass injectors and a tunable ECU that can allow him to change the A/F ratio easily..
i'm just tryin to make sure he knows that the comp ratio on the c5 is already up there and that witht he money he is spending on this thing he could just bolt that nice head of the c1 he's got and use it's (eeekkk..i am pretty sure i'm right here but i duno...) higher comp ratio to a c5 and save time and effort....
