Roller cam suggestions?

You never said what size engine. Other good things to included as far as info goes is tranny model, gear ratio and tire size along with intended useage of the car.
For a cool sound, as in like, "I got a cam in there baby!"
A tight centerline is what gives that chop chop chop sound. Look for a cam with a centerline of 110 for that sound and still have good drivabilty.
When you order the cam, just ask them for the springs they recomend for the cam. It is that easy. I recomend Crane cams because they have small roller cams. I have not notice them in the Comp Cams catolog unless it's a Magnum engine.
