That's incorrect. On a supercharged application with a free flowing exhaust, the cam shouldn't look too different from an NA cam as supercharged cars can take full advantage of exhaust scavenging unlike turbo applications in which case lower overlap is GENERALLY recommended as the high exhaust pressures can backup and contaminate the charge.

i'm doin a similar build but i'm puttin a twin screw supercharger on top. there are 2 things i'd change in your build though, the stock crank (from what i've been told by a very good engine builder in Nor Cal) the stock crank is good up to 1000hp BUT not under constant pressures and heat from a supercharger application (probably not wording it right) it'll do it with nirtous cause nitrous doesn't put on strain the whole entire time you drive. and beings that i'm thinking about running the same boost as you i'd ask your engine builder about this. also i was told to stay away from the LS7 lifters at the power level i'm lookin at, but for the life of me i can't remember why he said to stay away from them
. anyway thats my input good luck on your build!!!

stroking it is fun lol how much more did they quote for a forged 4" crank? that'd put you at 402CI
i'm goin through HKE for mine (iron forged 408) and i'm guessin it'll be about 5k for the engine since i'm goin to ask them for new pushrods, lifters and rockers and i'll ship them my heads and cam and have them put it all together then ship it assembled
