Product Details

COMP Cams is well-known for performance camshafts and valvetrain components. This Xtreme 4x4 hydraulic flat tappet camshaft and lifter kit is built for Ford's Big Block 385 series engines, specifically the 429 and 460 cubic inch displacements. If you're looking to wake up your F-250, F-150, or F-350 from the mid-70s through the mid-90s, this kit offers a solid upgrade path.

This kit includes the camshaft itself, a set of hydraulic flat tappet lifters designed to work with it, assembly lube to get everything started right, and decals. The X4 256H camshaft has a 210 degree intake and 218 degree exhaust duration at .050 lift, making it a popular choice for trucks that see a lot of street use but still want a noticeable improvement in power and torque. It's designed to fit right into your existing 429 or 460 engine without major modifications, making it a straightforward way to enhance your truck's performance.

Remember, this kit is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures to ensure the longevity of your new valvetrain components.
