COMP Cams Cam & Lifter Kit CB 270H-R10

This COMP Cams Magnum hydraulic roller camshaft and lifter kit, part number CL11-420-8, is built around a 215/215 duration profile. It's designed for daily driven street machines and works well with stock torque converters, making it a solid choice for improving the performance of your Chevrolet Big Block 396-454 engine. For 396 cubic inch engines, a gear ratio of 3.55 to 3.73 or higher is recommended to get the most out of this cam. Expect a slightly rougher idle than stock, which is typical for a performance camshaft of this nature.

The kit includes the camshaft itself, a set of hydraulic roller lifters, assembly lube to ensure proper break-in, and decals. This setup is intended for Chevrolet GEN IV Big Block engines that originally came with flat tappet camshafts. It's a popular upgrade for vehicles like the Chevrolet Chevelle, Camaro, and Impala from the late 60s and early 70s, offering a noticeable bump in power and responsiveness without requiring extensive modifications to your drivetrain. The roller design reduces friction compared to flat tappet systems, allowing for more aggressive cam profiles and improved durability.

When installing this kit, it's important to follow the included instructions carefully. While it works with stock converters, consider that headers are also recommended to help your engine breathe better and achieve optimal performance gains. This kit is not CARB approved and cannot be shipped to California.
