COMP Cams Cam & Lifter Kit CBVI 291Th R

If you're looking to get more out of your Chevrolet Big Block GEN VI engine, this COMP Cams Mutha' Thumpr hydraulic roller cam and lifter kit is a solid option. This kit is designed for high-performance street and strip applications, and it's built to work with engines requiring around 9:1 compression. You'll also need to pair it with an upgraded intake, gears, and headers to really make it sing. Expect a noticeable change in how your engine performs, especially at higher RPMs, though it will have a rougher idle than stock.

This kit includes the camshaft, lifters, assembly lube, decals, and instructions, so you have the essentials to get started. The hydraulic roller design means less friction and more efficient operation compared to flat tappet cams. For this cam to perform optimally, COMP Cams recommends a 2500+ RPM stall speed torque converter if you're running an automatic transmission. It's a well-built package aimed at enthusiasts who want a significant performance bump for their Big Block Chevy.

Keep in mind that this cam is intended for performance builds and will have a rough idle. It's also important to note that this part is not CARB approved and cannot be shipped to California. Make sure your vehicle's setup can support the demands of this camshaft for the best results.
