COMP Cams Cam & Lifter Kit CB 285C-R8

This COMP Cams Cam & Lifter Kit, part number CL11-706-9, gives you everything you need to get a solid roller camshaft and matching lifters installed in your Chevrolet Big Block engine. Inside this box, you'll find the CB 285C-R8 camshaft itself, a set of solid roller lifters designed to work with it, a tube of assembly lube to get everything started right, and decals for your engine bay. This kit is specifically designed for Chevrolet Big Block 396 to 454 cubic inch engines that originally came with a flat tappet camshaft, and it's a popular choice for high-performance applications like jet boats and river racing where reliable power is essential.

The CB 285C-R8 camshaft features a Marine 252/262 duration profile, meaning it has 252 degrees of intake duration and 262 degrees of exhaust duration at .050 inch lift. This profile is well-suited for engines built for demanding use, offering a noticeable bump in power and torque, especially in the mid to upper RPM range. Because it's a solid roller design, it requires roller lifters and associated valvetrain components, which are included here to ensure proper compatibility and performance. Solid roller setups are known for their ability to handle higher lift and RPMs compared to flat tappet designs, making them a strong choice for performance builds.

This kit fits a wide range of Chevrolet vehicles from the late 1960s through the early 1980s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup. It's important to note that this kit is intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the correct valvetrain components and clearances for a solid roller setup before installation.
