Im looking at putting in cams in my car. I have a 2002 gt with shorty headers, magnoflow catted x-pipe, magnapack catback, cold air, steeda pullies, intake spacer, bbk 75mm throttle body, c and L Plenum, 3:73, and an autologic chip. What would be a good lift on a cam for me and what type of horsepower gains am I lookking at getting with that.
