Product Details

The COMP Cams 94-600-10 Thumpr Hydraulic Roller Camshaft is a high-performance street cam engineered for Cadillac 425, 472, and 500 cubic inch V8 engines. Designed as a retro-fit hydraulic roller upgrade for engines originally equipped with flat tappet camshafts, this billet steel camshaft delivers a signature choppy, thumping idle quality along with real horsepower and torque gains across a broad powerband.

The Thumpr series grind profile combines an early exhaust valve opening, extended exhaust duration, and a generous intake/exhaust overlap window — characteristics that produce the aggressive, loping exhaust note that muscle car and street rod builders demand. With an operating RPM range of 2,000–5,400, this cam is well-suited to high-performance street builds and works with a stock torque converter, though it performs best when paired with a 2,000+ RPM stall converter and numerically higher rear gearing.
