COMP Cams Camshaft CRS XR280HR-10

COMP Cams is well-known for making performance parts that help engines run better. This Xtreme Energy camshaft is a hydraulic roller type, designed for Chrysler's LA series engines like the 273, 318, 340, and 360. If you're looking to get more out of your Mopar V8, a camshaft upgrade like this can make a notable difference in how the engine breathes and performs, especially at higher RPMs.

This particular camshaft, the XR280HR-10, has a duration of 230 degrees on the intake and 236 degrees on the exhaust. It's a retro-fit hydraulic roller, meaning it can be installed in engines that originally came with flat tappet cams, but you'll need the supporting components for a roller setup. For this cam to really shine, COMP Cams suggests pairing it with 3.91 or numerically higher gears, a compression ratio around 9.5:1, a torque converter with a stall speed above 2500 RPM, an aftermarket intake manifold, and headers. These components work together to help the engine take full advantage of the camshaft's improved airflow characteristics.

This camshaft fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the 1960s through the 1990s, including models like the Dodge Challenger, Plymouth Barracuda, and Chrysler Cordoba. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components for a hydraulic roller setup before installation.
