Product Details

This kit from COMP Cams gives you the camshaft, lifters, assembly lube, and decals needed to get started on an engine upgrade. It's designed for a range of V8 engines found in many classic American cars, including models like the Oldsmobile Cutlass Supreme, Buick Electra, and Chevrolet Caprice, from the late 1960s through the early 1990s.

The XE268H-10 camshaft is part of COMP Cams' Xtreme Energy line, known for producing noticeable torque gains across the RPM range. This particular grind is well-suited for street machines, offering a slightly rougher idle that many enthusiasts appreciate for its aggressive sound. It works best with an 1800 RPM or higher stall torque converter, which helps keep the engine from bogging down at lower speeds when the camshaft's more aggressive profile is active. This setup can make a real difference in how your vehicle feels off the line and during acceleration.

When installing a new camshaft and lifter kit, it's important to follow the included instructions carefully to ensure proper break-in and longevity. This kit is a solid option for anyone looking to wake up their older V8 engine with a popular and well-regarded performance camshaft.
