Also, yes some grs will be needed imo, and if you get a b-cam, or any aftermarket performance cam, you will need at least 3.55 grs, or steeper, or your car will be a dog on the lowend, my 3.27's, (like mentioned before earlier in the thread), are good on the highway, and im still launching hard, even smoking some 373'd stangs, but whatever you think you need.
good luck.
