COMP Cams Camshaft CBVI 291Th R7 Thumper

This COMP Cams Mutha' Thumpr camshaft is a hydraulic roller type designed for Chevrolet and GMC Big Block Gen VI engines. You'll receive the camshaft itself, ready for installation into a wide range of trucks and vans like the 1996-1999 Chevrolet C/K 2500 Suburban or the 2000 GMC Savana 3500. This camshaft is built for high-performance street and strip applications, and it's specifically tuned to produce a noticeable, rough idle that lets everyone know you mean business.

To get the most out of this camshaft, it requires a solid foundation. You'll need at least 9:1 compression, a torque converter with a 2500 RPM stall speed or higher, and you'll want to pair it with an upgraded intake manifold, proper gearing, and a good set of headers. These components work together to help the camshaft breathe and perform at its best, unlocking improved power potential for your Big Block.

When installing this camshaft, remember that it's designed for a more aggressive sound profile, so expect a rough idle. It's a well-built piece from COMP Cams, a popular name in performance engine components, and it's a solid option if you're looking to significantly change the character and performance of your Gen VI Big Block engine. Please note that this camshaft is not CARB approved and cannot be shipped to California.
