Best option? Since nobody here Id bet makes and dynos cams for a living call a cam manufacturer and they will give you the perfect cam. I like comp cams but to each his own. my but dyno isnt as accurate as their real dyno.
most ls carb cams have a tight lsa mainly around 110. mine is 110+4degrees of adv. Call jeoff at EPS(engine power systems). He custom grinds cams using comp grinds. he did mine.
