COMP Cams Camshaft Kit CB 291T HR-7 MT

When you're looking to get serious performance out of your Chevrolet Big Block engine, this COMP Cams Mutha' Thumpr camshaft kit is a solid choice. This K-Kit comes with everything you need to swap out your old flat tappet setup for a hydraulic roller camshaft, including the camshaft itself, lifters, valve springs, retainers, valve locks, valve stem seals, and a timing chain set. You also get assembly lube, decals, and instructions to guide you through the process.

This CB 291T HR-7 MT camshaft is designed for high-performance street and strip applications. It works best with at least 9:1 compression and requires a 2500+ RPM stall torque converter, along with intake, gears, and headers to really shine. Expect a rough idle, which is characteristic of these aggressive cams, but the payoff is a significant increase in power. The hydraulic roller design means less friction and wear compared to flat tappet systems, allowing for more aggressive lobe profiles and better performance.

This kit is a comprehensive package for upgrading your Chevrolet 396-454 Big Block engine. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Make sure your engine is originally equipped with a flat tappet camshaft to ensure proper compatibility with this hydraulic roller conversion kit.
