280rwhp and 315rwtq. I'd take it no higher than 5800-6000. Is your GT40 intake opening ported to allow for a 70mm TB? If not that may cause a slight restriction. I think the opening is 67mm. Are you gonna actually tune it or just make like 2 runs? Why the stock cam? At least you could do a before and after dyno for the cam. I wanna take my car to the dyno, but its too damn expensive cause the place charges through the roof! $100/2 pulls + $75 for a/f meter use + $25 for each extra pull + tax = over $200 What are they charging you? Are you gonna use a a/f meter to tune it? Good luck!
