COMP Cams Camshaft Kit CB XR297 R-10

This is the COMP Cams XR297 R-10 Xtreme Energy Solid Roller Camshaft Kit, designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts. If you're looking to significantly upgrade the performance and breathing capabilities of your big block Chevy, this kit is a comprehensive solution. It’s built for those who want a noticeable bump in power, especially in the mid-to-upper RPM range, making it a popular choice for performance builds.

What sets this kit apart is that it’s a complete package, meaning you get everything you need to swap out your old camshaft and associated valvetrain components. Inside the box, you'll find the XR297 R-10 solid roller camshaft itself, which features a 260/266 degree duration at .050 inch lift and .624 inch lift on both intake and exhaust. This aggressive profile is designed to maximize airflow and cylinder pressure for improved horsepower. Along with the camshaft, the kit includes high-performance lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a timing chain set to ensure precise camshaft timing, assembly lube for proper installation, and even decals and instructions to guide you through the process. This thoroughness helps ensure a smooth installation and a well-matched valvetrain.

Keep in mind that this is a solid roller camshaft system, which requires a different valvetrain setup and potentially modifications compared to a stock flat tappet system. It's not CARB approved, so it cannot be shipped to California. This kit is a serious upgrade for performance-oriented Chevrolet Big Block engines, offering a substantial improvement in power and responsiveness when installed correctly.
