COMP Cams Cam & Lifter Kit CB XR297 R10

This is the COMP Cams XE 260/266 Solid Roller Cam and Lifter Kit, designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts. If you're looking to significantly boost the performance and breathing capability of your big block Chevy, this kit is a solid choice. It replaces your stock flat tappet setup with a more aggressive solid roller system, which allows for higher lift and duration, ultimately leading to more power, especially at higher RPMs.

Inside this kit, you'll find everything you need to get started on your upgrade. It includes the XE 260/266 camshaft itself, which features a 260-degree intake and 266-degree exhaust duration at .050 lift, along with a .575" intake and .590" exhaust lift. You also get the matching solid roller lifters, which are crucial for the higher speeds and loads of a roller system. To ensure a smooth installation and break-in, COMP Cams includes assembly lube, and you'll also receive decals and instructions to guide you through the process. This kit is built for serious performance applications where maximizing airflow and power output is the goal.

Keep in mind that this kit is not CARB approved and cannot be shipped to California. For optimal performance and longevity with a solid roller setup, it's important to ensure your valvetrain components, including pushrods and valve springs, are compatible with the camshaft's specifications. Always refer to the included instructions for proper installation and break-in procedures.
