Product Details

This COMP Cams Xtreme Energy camshaft kit is built around the XE256H10 hydraulic flat tappet camshaft, featuring a 212 degrees of intake duration and 218 degrees of exhaust duration at .050 inch lift. This specific grind is designed to deliver strong torque through the low end and mid-range of the RPM band, while still maintaining a good, manageable idle. It’s a popular choice for AMC V8 engines like the 290, 304, 343, 360, 390, and 401, and fits a wide range of vehicles including the Jeep CJ series, Jeep Cherokee, and various American Motors models from the 1960s through the 1980s.

When you choose this K-Kit, you're getting a complete package to ensure a smooth and successful camshaft installation. It includes not only the camshaft itself but also the necessary lifters, valve springs, retainers, valve locks, and valve stem seals. For flat tappet applications like this one, COMP Cams also includes assembly lube to properly break in the new components. A timing chain set is also part of the kit, ensuring your engine's timing is set correctly with the new camshaft. You'll also find decals and instructions to guide you through the process.

This kit is a solid option for AMC engine owners looking for an improved powerband, especially in the crucial low and mid-RPM ranges where you do most of your driving. It’s important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to get the most out of your new camshaft.
