cam help

trying to decide wich cam setup would be better for my 350 tpi. right now im stock, but the cam will be going in with reworked heads and a Holly Stealth Ram. i dont know much about cams so any help is appreciated.


Cam that some of the NIFBA guys helped me pick out, just dont know if its too big for my needs or not.

Well the first cam listed is a flat tappet cam. The 2nd cam is for an LT-1 and of course a hydraulic roller cam. So like was posted above what block do you have?

the LT4 cam hands down, but you will need a chip to even get it to run.
good luck.
