Product Details

If you're looking to wake up the performance of your Chrysler LA-series engine, this COMP Cams Xtreme Energy camshaft and lifter kit is a solid choice. Designed for street machines and mild bracket racing applications, this kit aims to give your engine a noticeable bump in power and a classic lopey idle. It's built to work well with a 9.5:1 compression ratio and a 2800 RPM stall torque converter, making it a popular upgrade for those wanting more out of their Mopar V8.

This kit includes everything you need to get started: the camshaft itself, a set of solid lifters, assembly lube to ensure proper break-in, and decals for that finishing touch. The camshaft features a 236-degree intake and 242-degree exhaust duration at .050 inch lift, which is a well-known profile for delivering improved performance without being overly radical for street use. This profile helps your engine breathe better, especially at higher RPMs, contributing to that desired performance feel.

This camshaft and lifter kit is designed to fit a wide range of Chrysler LA engines, including the 273, 318, 340, and 360 cubic inch V8s. It's a great way to refresh the valvetrain and unlock more power from your classic Mopar. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures.
