    Has anyone had any good or bad experience with this cam. Comp Cam pt# 12-249-4. Its described as great in stock throttle body or crossfire. I am planning on running it in my 350 build up using 9.3 compression, edelbrock tbi perfomer intake manifold, stock exhaust manifolds and stock computer. It will be used in my full size blazer so low end and torque is all I am after with this combo.

    i didnt change anything since they said i didnt have to, but i figure if you do a custom chip, and a larger thortal body you would be able to take the cam to its full potential

    Cool! thats what I needed to hear. I will likely mod the tbi at later date but sure dont want to swap cams after the motor is in and have a cluster on my hands!

    If I go with the same cam on my 87 with vortec heads and edelbrock performer intake, headers and the Turbo City upgrade for the Vortec heads how much hp and torque would I be putting out or would it be worth it.
