Just go to www.compcams.com and look up the mutha thumper cam. In any hotrod, I always recommend running a vacume canister to help with power brakes. This cam is not hard on valve train, and is nothing crazy it just flat out works!
There are others out there running that cam in 4" stroke small blocks and they say they make some real good power and sound good too.
Here are the specs on the hydraulic roller cam Brian ground for me: 586/540 lift intake/exhaust, 236/242 @ 50 duration, 108 Lobe Separation Angle. It has a very small base circle to make the lifters work with the sloppy factory block. My car is a factory manual disc brake car. Its a pretty rough idle but throttle response is instant, tons of low end torque, and pulls very hard up top too. I still get a big rush stepping on it even after 1 1/2 years its been in there.
