COMP Cams Cam & Lifter Kit CRB XE284H-1

This kit from COMP Cams gives you the camshaft, lifters, assembly lube, decals, and instructions you need to get started on an engine upgrade. It's designed for Chrysler B and RB series engines, like the 383, 400, 413, 426 Wedge, and 440. This kit is a popular choice for street/strip applications where you're looking for improved performance over stock.

The XE284H-1 camshaft features a 240/246 degree duration at .050 lift, which is a notable step up from factory cams. This means you'll get a rougher idle, which is typical for performance cams of this size, and it really wakes up when the engine is spinning faster. To make the most of this cam, COMP Cams recommends a stall speed of 2800 RPM or higher and a compression ratio around 9:1. This combination helps the engine breathe better and make more power, especially at higher RPMs.

When installing this kit, remember that it's intended for off-road use and is not CARB approved, so it cannot be shipped to California. Make sure you have the right supporting modifications, like a torque converter with a higher stall speed, to match the cam's characteristics for optimal performance.
