CL126004 Chevrolet Thumpr Hydraulic Flat Tappet Cam And Lifter Kits

COMP Cams is bringing the musclecar sound back, and its nastier than ever! lets 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. 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.
