Man I hope you're planning on h-beam connecting rods and forged everything with a setup like that. You'd most certainly want lower compression pistons and twin intercoolers, or else sh*t blows up. Also I think ATI Prochargers are the authority on supercharging LT1's from most all sources I've ever consulted. Combination Motorsports sells one of their kits, with a few different components for an awesome price. They recognize where the ATI kit falls short and substitute as necessary, they know what they're doing.
