Now available for hydraulic flat tappet applications, COMP Cams® new Thumpr™ Camshafts are the hottest cam series to hit the streets in more than a decade. Street rodders and muscle car enthusiasts just can’t get enough of the incredible exhaust sound and equally impressive performance delivered by these innovative camshafts. Applying a new camshaft design concept originally created for sports car endurance racing, the COMP Cams® engineering team incorporated early exhaust 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 power output or streetability.

 

• Available for carbureted Small & Big Block Chevy, Ford 351 Windsor and Chrysler Small Block engines

• Long exhaust duration & other design characteristics produce a "serious power” sound

• Excellent hp gains & broad torque curve deliver real seat of the pants performance
