Home Thumpr™ Cams

Muscle car sound is back and nastier than ever; Thumpr™ Cams deliver incredible exhaust lope and impressive performance.

COMP Cams® designed the Thumpr™ series of camshafts to deliver the meanest-sounding idle on the block, but we didn’t skimp in the horsepower department in order to make it happen! Even the mildest Thumpr™ Cam profile produced significant horsepower and torque increases when put to the test. So rest assured that all of the musclecar attitude that your Thumpr™-equipped ride will be sporting is going to be backed up by the proven performance that you have come to expect from the horsepower experts.

Thumpr™ Cams are available in retro-fit hydraulic roller and hydraulic flat tappet versions for carbureted Small & Big Block Chevy, Ford 351 Windsor and Small Block Chrysler engines, as well as hydraulic roller drop-in replacements for Small Block Chevy factory roller engines. Featuring specially engineered profiles for each unique engine, these camshafts provide the perfect combination of an early intake valve opening, long exhaust duration and a generous amount of intake and exhaust overlap to maximize your engine’s nasty-idling characteristics without negatively impacting streetability.
