Product Details

This is the COMP Cams CRS Rx302S-R6 solid roller camshaft, designed for Chrysler's LA-series engines like the 273, 318, 340, and 360 cubic inch V8s. If you're building a serious street machine or a bracket car for the drag strip, this camshaft is engineered to handle sustained RPM and deliver strong performance in medium to large track environments. It's a mechanical roller camshaft, which means it's built for durability and high-rpm operation compared to hydraulic lifter setups.

To get the most out of this camshaft, COMP Cams recommends pairing it with an 11.5:1 compression ratio and a torque converter with at least a 4500 RPM stall speed. The cam specs, with a duration of 269 degrees intake and 276 degrees exhaust at .050 lift, are optimized for a good super street or bracket racing application. This means it offers a noticeable bump in power and responsiveness, especially in the upper RPM range, without being so radical that it makes the car undrivable on the street.

This camshaft fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the 1960s through the 1990s, including popular models like the Dodge Challenger, Plymouth Barracuda, and Chrysler Cordoba. It's a well-built component for enthusiasts looking to extract maximum performance from their Mopar LA engine. Please note that this camshaft is not CARB approved and cannot be shipped to California.
