x303 cam who runs one with a faily stock motor and whats needed to run one see my signature below??? i already know ill need stiffer valve springs i can use crane cams part # 96870...
That's a big cam for E7 heads, even ported I wouldn't think they would flow much past .500 lift. The X-cam is .542 lift IIRC. I would think a smaller cam like the F303 would be a better match. Whatever cam you choose, you will need to upgrade valvesprings, and have the pistons notched.
