COMP Cams is bringing the musclecar sound back, and it's nastier than ever! 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 our tech line is, "What camshaft will give my car that mean-sounding idle?" In an ongoing quest to provide you with the performance and sound you demand, COMP Cams engineering team proudly introduces the Thumpr series cam and lifter kits. The lobe profile and grind characteristics of these new Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. These Thumpr series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

COMP Cams CL12-600-4 - COMP Cams Thumpr Hydraulic Flat Tappet Cam and Lifter Kits I really like this cam!!! The Thumpr cam has good power range and a GREAT sound at idle. I do need a stall converter.

Camshaft sounds very good haven't drove it but a few miles seems a.little lazy on low end cruises good once above 1500 rpms.
