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.

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. 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. 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.
