Info

Have you ever been to the races and heard how nasty the cams sound? COMP Cams has developed the Thumpr series of cams that give you every day drivability, but have that nasty race engine sound. Pick the cam that fits your application, add a set of Comp Cam hydraulic lifters and you will be the talk of the town. 

High performance street/strip, needs 9:1 compression, 2500+ stall, intake, gears and headers, rough idle.
