Product Details

This COMP Cams Xtreme Energy solid roller camshaft features a 242/248 degree intake/exhaust duration at .050 lift, a design choice that helps it produce strong mid-range power while also delivering a radical idle. It's built for Chrysler's LA-series engines, specifically the 273, 318, 340, and 360 cubic inch V8s. This camshaft is intended for builds aiming for around 3000 RPM stall speed with a 10:1 compression ratio, making it a serious upgrade for performance-oriented Mopar engines.

As a solid roller camshaft, it requires specific valvetrain components like roller lifters, roller rocker arms, and often upgraded valve springs to function correctly and reliably. The Xtreme Energy series is known for its aggressive profiles, and this XR280R-10 model is no exception, providing a noticeable and aggressive idle sound that many enthusiasts appreciate. Its design focuses on maximizing power in the mid-range RPM band, which translates to strong acceleration and pulling power for vehicles like the Dodge Charger, Plymouth Barracuda, or Chrysler Cordoba from the 1960s and 70s.

This camshaft is a significant performance upgrade and is not CARB approved, meaning it cannot be legally shipped to California. It's designed for custom performance applications where emissions compliance is not the primary concern. Ensure you have the appropriate supporting modifications and valvetrain components to safely and effectively utilize the full potential of this camshaft.
