COMP Cams Camshaft Kit OL XE256H-10

When you're looking to wake up the engine in your classic Oldsmobile or other compatible V8, this COMP Cams Camshaft Kit K42-221-4 is a complete package. Inside this box, you'll find the XE256H-10 camshaft itself, along with a full set of hydraulic lifters, valve springs, retainers, and valve locks. It also includes valve stem seals, a timing chain set to ensure accurate valve timing, assembly lube for flat tappet applications, and decals to show off your engine's upgrade. This kit is designed to give you a noticeable boost in torque through the low and mid-range of the RPM band, while still maintaining a good, manageable idle.

This kit is built around the Xtreme Energy XE256H-10 camshaft, which is a popular choice for Oldsmobile 260 through 455 cubic inch V8 engines. It's engineered to provide strong torque from just off-idle up through the mid-range, making it feel much more responsive during everyday driving and when you need to accelerate. The hydraulic flat tappet design means it's designed for a smooth operation and a good idle quality, so you won't have to sacrifice comfort for performance. The included components like the valve springs and timing set are matched to work with the camshaft's specifications, ensuring proper valve operation and durability.

This kit fits a wide range of vehicles, including many from the 1967 model year and newer. You'll find it commonly installed in models like the Oldsmobile Cutlass Supreme, Buick Electra, and Chevrolet Caprice. Because this is a comprehensive kit, it includes almost everything you need to perform the camshaft swap, making the job more straightforward. Always refer to the included instructions for the best installation practices and any specific requirements for your vehicle.
