I have a 03 gt. I broke 2 pistons with ford racing svo blower with 10psi.... it had stock heads, cams, Water meth kit, x pipe, 39lbs injectors, 90mm maf, and sct tune. It made 355rwhp and i think 390tq. I blew the hose off the fule pressure senser and it went lean.... So now I built the bottom end Explorer block stock crank, falcon H-beam rods, 03 04 cobra pistons, pi intake for now Im gettin the eldelbrock victory jr. later. 3.73 gears 3650trans. I was looking at the cushman stage 3 cams for the trick flow tw 38cc 185cc heads. I want to spin it 7000rpms+. I want to know if someone knows of a good rpm cam to run that is under or at .600 lift. thanks
