COMP Cams Camshaft CRB3 XR286HR-10

COMP Cams is well-known for its performance valvetrain components, and the XR286HR-10 camshaft is a prime example of their expertise in pushing engine performance. This camshaft is specifically designed for Chrysler B and RB series engines, including the 383, 400, 413, 426 Wedge, and 440 cubic inch V8s. It utilizes a 3-bolt camshaft design for secure installation and is a retro-fit hydraulic roller camshaft, meaning it brings modern roller technology to older engine designs without requiring extensive modifications.

The XR286HR-10 features a 236-degree intake duration and a 242-degree exhaust duration at .050 inch lift, with a lobe separation angle of 107 degrees. This aggressive profile is intended for engines built for serious performance. To get the most out of this camshaft and ensure proper operation, it's recommended to pair it with a gear ratio of 3.91 or higher, a compression ratio of 9.5:1 or greater, and a torque converter with a stall speed of 2800 RPM or more. You'll also need to use headers for exhaust scavenging. Expect a rough idle with this camshaft, which is characteristic of its high-performance nature.

This camshaft is not CARB approved and cannot be shipped to California. It is important to note that this part is subject to California's Proposition 65 warning.
