COMP Cams Camshaft Kit CB XR292R-10

If you're building a Pro Street Chevrolet Big Block for serious performance, this COMP Cams Xtreme Energy Solid Roller Camshaft Kit is a solid choice. This kit is designed for engines like the 396, 427, and 454, and it's meant for applications where you're pushing the limits, like in a Pro Street setup. It's a complete package to get you started on a high-performance build.

This kit includes the XR292R-10 solid roller camshaft, which features a 254 degrees of intake duration and 260 degrees of exhaust duration at .050 lift, along with .632 inches of lift on both sides. Solid roller cams like this one are known for their ability to handle higher RPMs and provide more aggressive valve events, which translates to significant power gains, especially in the upper RPM range. To make the most of this cam, you'll need a good intake and exhaust system, a compression ratio of 11:1 or higher, and a torque converter with at least a 3500 RPM stall speed. The kit comes with the camshaft, lifters, a timing chain set, assembly lube, decals, and instructions, so you have the essential components to begin installation.

This kit is a significant upgrade for your Big Block Chevrolet and is best suited for those looking to maximize power for street and strip applications. Remember that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure optimal performance and longevity of your new camshaft setup.
