COMP Cams Cam & Lifter Kit CB XR274 R10

This COMP Cams Cam and Lifter Kit, part number CL11-770-8, gives you the core components to upgrade your Chevrolet Big Block engine. Inside this kit, you'll find the XE 236/242 solid roller camshaft, a set of matching lifters, assembly lube to get everything started right, and even some decals and instructions from COMP Cams. This kit is designed for power touring applications, meaning it's built to provide reliable power for cruising and spirited driving, and it's known for being easy on other engine parts while still delivering notable performance gains. It's a solid option for those looking to get more out of their 396, 427, or 454 cubic inch engines.

The XE 236/242 camshaft profile is a popular choice for its balance of performance and drivability. It's engineered to work well with engines that have a 2500 RPM or higher stall torque converter, which helps keep the engine in its power band during acceleration. While it offers a rougher idle characteristic that many enthusiasts appreciate for its aggressive sound, it's also known for its reliability and consistent power delivery. This kit is intended for Chevrolet Big Block engines originally equipped with flat tappet camshafts, and it fits a wide range of vehicles including models like the Chevrolet Impala, Chevelle, and C10 Pickup from the late 60s through the mid-70s.

When installing this kit, remember that a solid roller camshaft requires careful attention to lubrication during assembly, which is why the included assembly lube is so important. It's also worth noting that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure your engine setup, including the torque converter and valvetrain, is compatible with the specifications of this solid roller camshaft.
