1 7/8" Headers
True Duals
85mm maf!
Stock LS7 Intake!!

That is extremely nice considering there is some power left on the table. The stock pulley, waterpump, unported intake, relatively* small maf, and throttle body could all be swapped out for some mega power. I'd like to see this thing with a 100mm lid, 100mm maf, 100mm tb, ported intake, underdrive pulley, and EWP. I bet it would make 630-645rwhp.
