COMP Cams Camshaft Kit CB XR297R-10

If you're looking to significantly boost the performance of your Chevrolet Big Block engine, this COMP Cams camshaft kit is a solid choice. Specifically designed for the 396 through 454 cubic inch GEN IV engines that originally came with flat tappet camshafts, this kit aims to unlock more power and improve engine response. It’s a comprehensive package that includes everything you need to get started on a serious engine build.

This kit features the XE 260/266 Solid Roller camshaft, which is known for its aggressive profile and ability to handle higher RPMs. Solid roller camshafts generally offer better lift and duration control compared to hydraulic flat tappets, leading to improved airflow and more power, especially in the mid to upper RPM range. The kit also comes with the necessary lifters, a timing chain set for precise valve timing, and assembly lube to ensure proper installation and break-in. This attention to detail in what's included helps make the installation process smoother.

When undertaking an upgrade like this, it's important to consider that a camshaft change often requires other supporting modifications to maximize its potential and ensure engine longevity. This includes ensuring your valvetrain components are up to the task and that your fuel and ignition systems can keep up with the increased airflow. This COMP Cams kit is a well-built foundation for a performance-oriented Big Block build.
