COMP Cams Camshaft Kit CB XS290S-10

When you're looking to wake up your Chevrolet Big Block engine, this COMP Cams Xtreme Energy Camshaft Kit is a solid choice. What you get in this box is a complete package: the camshaft itself, a full set of lifters, new valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure your valvetrain stays perfectly synchronized, plus assembly lube to get everything started right. You'll even find some decals and instructions to help you through the process.

This particular kit, the CB XS290S-10, is designed for Pro Street and bracket racing applications. It's built to perform, but it does require supporting modifications to really shine. Think a good intake manifold, headers, and a rear gear ratio that matches your setup, along with a torque converter rated for 3500 RPM or more. This kit is intended for Chevrolet Big Block engines like the 396, 427, and 454 that originally came with a flat tappet camshaft. It's a popular upgrade for vehicles like the Chevrolet Chevelle, Camaro, and Impala from the late 60s through the mid-70s.

Installing a camshaft kit like this is a significant job, usually involving removing the engine's front cover, oil pan, and cylinder heads. It's a project that requires careful attention to detail and proper assembly procedures. COMP Cams is a well-known name in performance engine parts, and this kit is put together to give you a comprehensive solution for a serious engine build.
