Since I have the car apart, how far should I go. I would really like to do a cam and maby some heads if I couold do it cheap enough. Is the GT40 stuff that much of an improvement over what I have now as far as heads and intake go. I am going to do an intake of some kind but I am not sure what one yet. My goal for the car would be 300-350hp at the rear wheels before spray. Can I do that with GT40 heads, intake and a cams of some kind? Will also be doing long tubes, X pipe, cat back and either 3.73's or 4.10's at the same time.
