THUMPR BBC CAMSHAFTS
HATED BY NEIGHBORS, ENVIED BY FRIENDS...

Musclecar Sound is back and nastier than ever; Thumpr Cams deliver incredible exhaust lope and impressive performance for your Big Block Chevy

  • Retro-Fit hydraulic roller design will fit all flat tappet equipped 1965-1996 Big Block Chevys 396-454

  • Long exhaust duration and other grind characteristics produce a powerful, hard-hitting exhaust note

  • Excellent Horsepower gains and broad torque curve deliver real seat of the pants performance

  • Designed for use with the latest in valve train component advancements such as Beehive Valve Springs, Pro Magnum Roller Rockers, and Magnum Pushrods.

 

When the Big Block Chevrolet engine debuted in 1965, it revolutionized the high performance world. The new COMP Cams® Thumpr™ Camshafts take the original Mark IV engine one step further with a line of three retro-fit hydraulic roller camshafts that not only delivers excellent power and torque gains, but includes another important feature – true high performance camshaft sound. For those folks who desire not only the performance but the sound of power, COMP Cams® Thumpr™ Camshafts are the perfect component for the job.

These street compatible camshafts fit 1965 through 1995 Big Block Chevrolet 396-454cid engines that originally came equipped with flat tappet lifters (to fit 1965 and early 66 model years, special modification of the rear journal is required – available through COMP Cams®). Thumpr™ Camshafts offer the choice of three different horsepower levels to meet most engine building requirements. By “tightening” the lobe separation angle of the camshaft, the COMP Cams® engineering team has delivered the “holy grail” for performance enthusiasts – unbelievable sound quality and real horsepower gains. Best of all, the Thumpr™ camshafts deliver all these benefits without sacrificing drivability.
