My buddies car is almost built and were starting to debate what it's gonna put down. It is a 99 Cobra with a forged SB (H-Beams and Probe 18cc) he is using stock 99 cobra heads, comp cams blower cams (not sure on specs) and a stock manifold. The car has a D1SC and will be pullied for 15 and 18 pounds depending on the tune (SCT 4 Bank). I was thinking it should break 600hp on 15 pounds and might clear 650 on 18 pounds. Anybody with a similar set-up? How much power is he leaving on the table with stock heads and intake, because he was debating having them ported. Car is being put together as we speak and when it hits the dyno ill let you guys know what it lays down. Thanks....
