Comp Cams Big Mutha' Thumpr Nitrided 243/257 Hydraulic Flat Camshaft (67-74 Big Block V8 Corvette C2 & C3)Find parts that fit my vehicle

COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things grab our attention at a car show or cruise-in like a thumping, high performance idle. In fact, one of the most frequent questions from customers is, "What camshaft will give my car that mean-sounding idle?" For the performance and sound you demand, COMP Cams engineers introduce the Thumpr camshafts—a new series of hydraulic flat tappet cams. The lobe profile and grind characteristics of Thumprs use 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. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in several grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range.
