Comp Cams Thumpr Series Hydraulic Flat Tappet Camshaft for GM


Thumpr Cam by Comp Cams

The Muscle-car sound is back and nastier than ever, Thumpr™ Cams deliver incredible exhaust lope and impressive performance

Let’s face it, few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In fact, one of the most frequent questions fielded when customers call the CAM HELP® tech line is “what cam will give my engine a mean-sounding idle?” In response to this popular demand, the COMP Cams® engineering team proudly introduces the Thumpr™ series of camshafts.

The Thumpr™ Camshafts are a new series of hydraulic flat tappet designed for use in Small & Big Block Chevy, Ford 351 Windsor and Small Block Chrysler engines.

The reason that the new Thumpr™ Camshafts have such an aggressive exhaust note is that the lobe profiles and grind characteristics chosen by the COMP Cams® engineers produce a combination of early exhaust valve opening, long exhaust duration and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams without negatively impacting the power output or streetability.

Thumpr™ Camshafts are available in three different grind profiles for each engine, all of which will produce a rough, racy exhaust note and impressive amounts of horsepower and torque. Their cutting-edge design means that they will deliver a substantial power increase over "tamer" camshaft grinds without sacrificing reliability or ease of maintenance
