COMP CAMS XTREME ENERGY XE270 and COMP CAMS XTREME ENERGY 262 . the xe270 is good from 1800- 5800, and the ex626 is good from 1400 to 5400. which is better to go in a stock stang and i will be getting new valve spring too. but i want a procharger in a couple of years would it hurt to put vt cams in now. need info any at all would help thank you
