COMP Cams is bringing the muscle car 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 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 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. 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.

Why are Performer RPM cam and lifter kits the heart of the Total Power Package? Because Edelbrock designs them to perfectly match the powerband of their Performer RPM series of intake manifolds. They do this by testing and tuning them together on engine dynamometers for maximum performance. There's no guesswork about parts compatibility, and you can be sure that all of the combinations will perform. The kits are recommended for high-performance street and strip use. Their powerband is from 1,500 to 6,500 rpm, and they maintain 10 to 12 in. of vacuum at idle.
