COMP Cams Cam & Lifter Kit CB XS256S-10

If you're working on a Chevrolet Big Block engine like the 396, 427, or 454, this COMP Cams Xtreme Energy camshaft and lifter kit is a solid option for improving its performance. It's designed to give you strong torque right from the low end and through the mid-range, making it feel more responsive when you're driving around town or pulling away from a stop. Plus, it's set up to provide a good, manageable idle, so you won't have to worry about it being too rough.

This kit includes the camshaft itself, a set of lifters, assembly lube to make sure everything goes together smoothly and lasts, and some decals and instructions to help you out. It's built for Chevrolet GEN IV Big Block engines that originally came with flat tappet camshafts, covering a wide range of vehicles from classic Bel Airs and Impalas to Chevelles and Corvettes from the 60s and 70s. The Xtreme Energy series is well-known for giving you that improved low-end and mid-range pull without sacrificing too much drivability.
