Product Details

This is the COMP Cams XS268S10 XE camshaft, a solid flat tappet grind designed for Chrysler 273, 318, 340, and 360 cubic inch LA engines. It's built for street and strip applications, aiming to give you a strong mid-range power band, especially when paired with a 9.0:1 compression ratio and a 2500 RPM stall torque converter. This camshaft fits a wide range of vehicles, including popular models like the Dodge Challenger, Plymouth Barracuda, and Chrysler Cordoba from the 1960s through the 1980s.

The Xtreme Energy series from COMP Cams is known for its aggressive lobe profiles, and this XS268S10 is no exception, featuring 230 degrees of intake duration and 236 degrees of exhaust duration at .050 inch lift. These specifications are chosen to provide a noticeable increase in performance over stock cams, particularly in the crucial mid-RPM range where you'll feel it most during acceleration. It's a well-built component for enthusiasts looking to extract more performance from their Mopar LA V8.

When installing this camshaft, remember it's a solid lifter design, which requires more precise valve adjustment than hydraulic lifters. Ensure you have the correct valve springs to match the camshaft's lift and duration, and always follow the manufacturer's recommended break-in procedure to properly seat the cam and lifters.
