COMP Cams Cam & Lifter Kit CS X4 254H-1

If you're looking to wake up the performance of your classic Chevrolet V8, this COMP Cams CS X4 254H-1 hydraulic flat tappet cam and lifter kit is a solid option. This kit is designed for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 up to 400 cubic inches. It's a popular choice for those rebuilding or modifying engines in vehicles like the Chevrolet Camaro, Corvette, or C10 trucks, aiming for improved power and torque.

This kit includes the camshaft, matching hydraulic lifters, assembly lube, and decals, so you have the essential components to get the job done. The Xtreme 4x4 grind offers a 210/218 degree duration at .050 lift, which is a noticeable bump over stock, providing better breathing for the engine, especially in the mid-range. It's important to verify your engine uses a flat tappet camshaft, as many later model Small Blocks (especially from 1985 onward) switched to factory roller camshafts, and this kit is not compatible with those or LS-based engines.

When installing a new camshaft and lifter set, it's always a good idea to follow the included instructions carefully and ensure proper break-in procedures are followed to seat the new components correctly. This kit is a well-built upgrade for enthusiasts looking to get more out of their traditional Chevy V8.
