COMP Cams Camshaft Kit CRB XS274S-10

COMP Cams has a long history of making serious performance engine components, and this CRB XS274S-10 camshaft kit is built for those looking to get more out of their Chrysler B or RB engine. This kit is designed for street/strip use, aiming for strong mid-range power, and works well with a 9.5:1 compression ratio and a torque converter with a 2800+ stall speed. It’s a comprehensive package that includes the camshaft itself, lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, and assembly lube, along with decals and instructions to guide you through the installation.

This kit is intended for Chrysler 383, 400, 413, 426 Wedge, and 440 cubic inch engines. The XS274S-10 camshaft has a duration of 236 degrees on the intake and 242 degrees on the exhaust, designed to provide a noticeable bump in performance, especially in the mid-RPM range. The included valve springs are matched to the camshaft's profile to ensure proper valve control at higher engine speeds. This is a solid option for anyone rebuilding or modifying their engine for more aggressive street driving or track use.

When installing this kit, ensure you follow the included instructions carefully, especially regarding valve spring installation and timing. This kit is a multi-fit application, compatible with a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 1950s through the late 1970s, including models like the Dodge Charger, Chrysler New Yorker, and Plymouth Barracuda. Please note that this part is not CARB approved and cannot be shipped to California.
