Product Details

COMP Cams is well-known for making performance parts that help engines run better. This kit is built around their Xtreme Energy camshaft, designed to give your Chevrolet Big Block engine an improved power band. It’s a hydraulic flat tappet setup, meaning it uses lifters that don’t require constant adjustment, making it a popular choice for many builds. This kit is specifically for Chevrolet 396 to 454 cubic inch big block engines that originally came with flat tappet camshafts.

When you’re looking to get more out of your big block, a new camshaft and lifter kit like this one can make a notable difference. The XE256H-10 camshaft has a 212-degree intake and 218-degree exhaust duration at .050 inch lift, which is a solid profile for street performance. It’s designed to work well with a wide range of Chevrolet vehicles, including models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Biscayne, and 1973-1974 Chevrolet Blazer, among many others. This kit comes with everything you need to get started: the camshaft, lifters, assembly lube to ensure proper break-in, and decals.

Installing a camshaft is a significant job, and this kit is intended for those who are comfortable with engine teardown and reassembly. It’s a well-built package that offers a good balance of performance and reliability for your classic Chevrolet big block.
