BBC Thumpr Series Cam CB279T H-107

The BBC Thumpr Series Cam CB279T H-107 by COMP CAMS is a purpose-built hydraulic roller camshaft engineered for big-block Chevrolet engines seeking aggressive street and strip performance. Designed for enthusiasts and mechanics who demand a visceral, audible exhaust note paired with responsive throttle characteristics, this cam delivers the signature "thump" that separates serious builds from stock monotony. Whether you're upgrading a restomod, street rod, or weekend warrior, the Thumpr Series occupies the sweet spot between drivability and head-turning presence.

This hydraulic roller design minimizes valve train wear while maximizing lift and duration characteristics across the RPM band, a critical advantage over flat-tappet alternatives in high-mileage or performance applications. The CB279T profile is specifically tuned to exploit the BBC's large displacement and breathing capacity, translating into improved scavenging and cylinder filling—the mechanical foundation of the distinctive exhaust character Thumpr cams are known for. Roller followers reduce friction losses, allowing more of the engine's potential to reach the wheels rather than being consumed by internal drag.

Big-block Chevrolet owners—from 396 through 454 applications—will find this cam compatible with stock or upgraded valve train components, provided proper clearancing and spring rates are verified during installation. Experienced builders should confirm that existing pushrods, rocker arms, and intake manifold geometry accommodate the increased valve lift; COMP CAMS' engineering assumes quality supporting modifications. This is an ideal choice for naturally aspirated BBC builds where torque delivery and acoustic signature matter as much as peak horsepower numbers.
