What's in the Box

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.

A sweet sound to my ears

April 20, 2016
My neighbors do not like me anymore since I put the camshaft in my 427. They wake up every morning when I go to work. (I go early)
Yes, I recommend this product.

This big block chevy "thumpr" cam works for street/strip, needs 9.5:1 compression, 2800+ stall, intake, gears and headers, very rough idle. Stock valve springs can not be used, stock lifters and rockers are ok. It is always recommended to use new lifters when installing a new camshaft.
