from. Any suggestions on how.? This is my first project car, so please forgive my ignorance. The car also has a R700 trans, and borge warner posi. The best estimate I have gotten so far is that I am only getting about 160 hp. I want to bring it up to around 300hp.
Thank you for the suggestions. I do have hooker headers on it now. I will definitely look into these suggestions. Thank you very much.
