COMP Cams Camshaft Kit CS XE274H-10

This is the COMP Cams Xtreme Energy XE274H-10 camshaft kit, designed to give your Chevrolet Gen 1 Small Block engine a serious boost in mid-range torque and throttle response. If you're looking to wake up an older Chevy V8, this kit is a solid option, especially if you're running a 2200+ stall speed torque converter. It's built for engines like the popular 350, but also works with a wide range of other displacements from 262 up to 400 cubic inches.

What makes this kit stand out is that it's a complete package, 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 for reliable timing, assembly lube for proper installation, and even some decals and instructions to guide you. This comprehensive approach helps ensure a smooth installation and a well-matched valvetrain.

It's important to note that this kit is specifically for flat tappet camshaft engines. GM started phasing in roller camshafts around 1985, so you'll want to confirm your specific engine uses a flat tappet setup before ordering. Removing the intake manifold or timing cover is the best way to check. This kit is not compatible with LT1/LT4 engines or any LS-based V8s. For 1955-1957 265 engines, a specific oiling groove on the fifth cam journal is required, so reach out if you have one of those early blocks.
