Alright, I bought an engine from an '88 mustang. Complete stock bottom end and GT40 heads (3 bar and 1.54" exhaust valves, 65cc chambers). The motor received an alphabet cam (e) with the heads. The motor is going into a classic mustang with a 5 speed swap...
1) is worth a cam swap with the technological advances in past 20 years?
2) I called comp cams and they couldn't tell me what I would have to do (ie machinine work to heads) in order to run a thumper cam. They told me not to run extreme energy and said that I should run a 35-440-8 cam...but again couldn't tell me if it had too much lift for GT40 heads...anyone running this cam? What had to be done?
Anyways, I don't want to have to take the heads off to have them machined because I might as well get AFR 165'S if I go down that rabbit hole.
