COMP Cams Camshaft Kit CRB XE285Hl-10

If you're looking to wake up the performance of your Chrysler B or RB series engine, this COMP Cams Camshaft Kit, part number K21-228-4, is a solid option. This kit is built around the Xtreme Energy HI-LIFT XE285HL-10 camshaft, designed for hot street applications. It's a hydraulic flat tappet cam that works well with a 10:1 compression ratio, lower rear-end gears, headers, and a torque converter with a stall speed of 3000 RPM or higher. You can expect a strong pull in the mid-range, though it will have a noticeable, rough idle that lets everyone know you mean business.

This isn't just a camshaft; it's a complete K-Kit, meaning it includes everything you need to get the job done right. Inside, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure your valvetrain is perfectly synchronized. For flat tappet applications, COMP Cams even includes assembly lube to help with the break-in process, along with decals and detailed instructions to guide you through the installation. This kit is designed to fit a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 1950s through the late 1970s, including popular models like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker.

When installing this camshaft, remember that it's intended for performance builds where a rough idle is acceptable. Ensure your engine is set up with the supporting modifications mentioned – 10:1 compression, lower gears, and a higher stall converter – to get the most out of this cam's aggressive profile. This kit is a comprehensive package for enthusiasts looking to significantly improve their engine's mid-range power and overall performance.
