COMP Cams Camshaft Kit CS XE250H-10

The COMP Cams Xtreme Energy XE250H-10 camshaft kit is built around a hydraulic flat tappet camshaft featuring a 206-degree intake and 212-degree exhaust duration. This specific grind is known for generating strong torque and providing excellent mileage, all while maintaining a smooth idle, making it a popular choice for rebuilding or upgrading Chevrolet Gen 1 Small Block engines. It's designed to fit a wide range of these classic V8s, including popular models like the Chevrolet C10, Camaro, and Corvette, as well as many trucks and commercial vehicles from the 1980s and early 1990s.

This is a complete K-Kit, meaning it includes everything you need to get the job done right. Beyond the camshaft itself, you'll find new lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure proper valve timing, assembly lube for installation, and even decals and instructions to guide you through the process. This comprehensive approach helps ensure a smooth installation and reliable performance for your engine build.

It's important to verify your specific engine configuration before ordering. This kit is intended for engines with flat tappet camshafts and does not fit factory roller Small Blocks built from 1985 and newer, nor does it fit any LS-based engines. For 1955-1957 Chevrolet 265 engines, a specific oiling groove modification may be required. Always consult your vehicle's service manual or inspect the block to confirm your engine type.
