COMP Cams Camshaft CRS XR286R-10

Starting with a solid roller design, this COMP Cams Xtreme Energy camshaft is built for Chrysler's LA-series engines, specifically the 273, 318, 340, and 360 cubic inch V8s. The Xtreme Energy profile is engineered to give you quicker valve opening, which translates to more area under the lift curve. This means you get increased responsiveness and noticeable gains in both torque and horsepower, especially in the upper RPM range. It's designed to boost performance without making your vehicle uncomfortable to drive or sacrificing essential creature comforts like power brakes, as it still provides adequate vacuum for accessories.

This camshaft is a solid option for carbureted applications, but you'll see its best performance when paired with an aftermarket intake manifold, lower gear ratios, headers, and a free-flowing exhaust system. For optimal results, COMP Cams suggests a 3300+ RPM stall speed torque converter and a compression ratio of 10:1. You can expect a strong top-end pull and a distinct, race-inspired idle that lets everyone know you mean business. This camshaft fits a wide range of vehicles, including classic Mopar muscle cars like the Dodge Challenger and Plymouth Barracuda, as well as trucks and other Chrysler models from the 1960s through the 1990s.

When installing this camshaft, remember that it's a solid roller type, which requires specific lifters and potentially upgraded valve springs to match. Always refer to the manufacturer's installation instructions for detailed guidance on proper setup and break-in procedures to ensure you get the most out of this performance upgrade.
