COMP Cams Camshaft Kit CB XS256S-10

Starting with a 218/224 degree intake/exhaust duration split, this COMP Cams Xtreme Energy camshaft kit is built for Chevrolet Big Block engines originally equipped with flat tappet camshafts. This kit is designed to give you strong torque through the low end and mid-range of your engine's power band, while still maintaining a good, manageable idle. It's a solid option for drivers looking to improve the performance of their classic Chevrolet, like a 1967 Chevelle or a 1970 Impala, without sacrificing everyday drivability.

This isn't just a camshaft; it's a complete K-Kit, meaning you get everything you need to get the job done right. Inside the box, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. COMP Cams also includes a timing chain set to ensure your engine's timing is spot on, plus assembly lube specifically for flat tappet applications. You'll even get decals and instructions to help guide you through the installation process. This comprehensive approach means you won't be scrambling to find compatible parts, making the installation smoother.

When you're rebuilding or upgrading a big block Chevrolet, having a well-matched set of components is key. This kit aims to provide that synergy, focusing on a powerband that's effective for street use and general performance applications. It's a well-built package designed to bring out the best in your 396, 427, or 454 cubic inch engine.
