2500HD 6.0 N/A "1 day" build

My LQ4 is a 2002 and has the 75 or 78mm throttle body and opening- its pretty small.
So NNBS intake manifold? Looks like I'll need one of those. I swear I've read the LQ4 intake with the small throttle body handles 500hp? or 550hp?

Busted a spare LQ4 intake out of the garage and did some minor porting, gonna see if anyone's got a spare 3 bolt throttle body laying around thats a 80 or 85mm unit-
depends on how large I can bore the opening out in the intake manifold (factory hole is 75mm behind the throttle body, tapers down to 73mm, then opens back up to 75mm when the cavity opens at the top). Like I said, IF it can be bored to at least 80mm, I'll stick the spare on it and go check the KPA readings to see if its gonna work. If not, I'll go grab a NNBS intake.
