Product Details

If you're looking to get more performance out of your Chrysler B or RB engine, this COMP Cams Camshaft Kit is a solid option. This kit is designed for street/strip applications and is built around the XE284H camshaft, which features a 240/246 degree duration and .488/.491 lift. It's a hydraulic flat tappet camshaft that works well with a 9:1 compression ratio and requires a torque converter with at least a 2800 RPM stall speed. You can expect a rough idle with this setup, which is typical for performance cams of this size.

This isn't just a camshaft; it's a complete K-Kit designed to give you everything you need for a successful installation and improved performance. Inside the box, you'll find the camshaft itself, a set of hydraulic lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure your engine's timing is spot on, plus assembly lube specifically for flat tappet applications. COMP Cams even includes decals and detailed instructions to guide you through the process. This kit is designed to fit a wide range of Chrysler B and RB engines, including popular models like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker from the late 50s through the late 70s.

When installing a camshaft like this, it's important to have the right supporting components. COMP Cams recommends a minimum of 9:1 compression and a 2800+ RPM stall speed torque converter for optimal performance with this XE284H camshaft. Make sure you're prepared for the rougher idle characteristic that comes with a more aggressive camshaft profile. This kit is a comprehensive package aimed at significantly changing your engine's powerband for performance driving.
