Hi Im Looking for a cam to install in my 93 z28. I just picked the car up this past year an it primary use is racing. Its been rebuilt in 2010 and as far as i was told the only real internal upgrades were roller-rockers. Why they didnt put a better cam in is beyond me. Any way i was running are local hill climb and i seemed to be ******* it goin up the steep parts. The car was dyno tuned spit out 298 at the rear. Its a 6speed with a spooled rear an 3.73 gears. Fully gutted with a full cage. I think a good cam would make a world of difference in it. something to keep the mid range power up. I have a 95 z28 also which is my daily driver i put a compcam in that mild one changed the springs to heavier ones an all that car just seems like it pulls an pulls. but thats a A4 with stock rear 3.42 gears an stock tire size. Im basically looking for any suggestions on a good cam that can take the beatin of running all day that will make good power mid range or all over for that matter.
