Muscle car sound is back and nastier than ever. Thumpr Cams deliver incredible exhaust lope and impressive performance. Let's face it, few things serve to grab our attention more than a car with a thumping, high performance idle. Although the cam design gurus at COMP Cams designed the Thumpr series of camshafts to deliver the meanest-sounding idle on the block, they weren't about to skimp in the horsepower department in order to make it happen! Even the mildest Thumpr Cam profile produced significant horsepower and torque increases when put to the test in the COMP Performance Group research and development center. So rest assured that all of the muscle car attitude that your Thumpr-equipped ride will be sporting is going to be backed up by the proven performance that you have come to expect from the horsepower experts at COMP Cams.

These camshafts provide the perfect combination of an early intake valve opening, long exhaust duration and a generous amount of intake and exhaust overlap to maximize your engine's nasty-idling characteristics without negatively impacting streetability. Without question, Thumpr cams are in a class by themselves when it comes to serious "seat of the pants" performance and aggressive idle.

The Thumpr 283THR7 is a high performance street camshaft with a choppy/thumping idle. A stock torque converter is acceptable with this camshaft, but works best with a 2000+ stall torque converter and gears.
