COMP Cams Camshaft Kit CB 291T HR-107 M

This COMP Cams Mutha' Thumpr camshaft kit features a 235/249 degree duration at .050 inch lift and a 107-degree lobe separation angle. It's built for a hydraulic roller valvetrain, which means less friction and more consistent valve timing compared to flat tappet cams. This kit is designed for high-performance street and strip applications, and it's specifically intended for Chevrolet Big Block engines like the 396, 427, and 454 cubic inch V8s. You'll find it fits a wide range of classic Chevrolet vehicles, including models like the 1967-1975 Camaro, 1967-1974 Corvette, and 1968-1980 C10 pickups.

To get the most out of this camshaft, you'll need to pair it with other performance components. The manufacturer recommends at least a 9.0:1 compression ratio, a torque converter with a 2500 RPM or higher stall speed, and upgraded intake, gearing, and headers. Expect a noticeable, rough idle characteristic that lets everyone know you've got some serious power under the hood. This kit is a well-built option for those looking to significantly enhance their Big Block's performance for drag racing or spirited driving.

When installing this camshaft, remember that it's a performance part and requires supporting modifications for optimal function. It's also important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding break-in procedures and component compatibility to ensure the longevity and performance of your engine.
