Thumpr 227/241 Hydraulic Roller Camshaft, For Chevrolet Big Block 396-454. Brandname: Comp Cams Part Number: 11-600-8 Description. Comp Cams is bringing back the musclecar soundand it's nastier than ever!Few things grab our attention at a car show or cruise night more than a car with a thumping high performance idle. In an ongoing quest to provide you with the performance and sound you demand, Comp Cams' engineering team proudly introduces the Thumpr retrofit hydraulic roller camshafts. They are a series of camshafts designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics 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. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles.
Each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Comp Cams Thumpr Series camshafts feature a cutting-edge hydraulic roller design that delivers a substantial power increase over identical hydraulic flat tappet grindswithout sacrificing reliability or ease of maintenance. Exhaust Valve Lift: 0.53. Intake Valve Lift: 0.547. Basic Operating RPM Range: 1,900-5,500.
