COMP Cams Cam & Lifter Kit CS XS290S-10

This is the COMP Cams Xtreme Energy CS XS290S-10 solid flat tappet camshaft and lifter kit, designed for Chevrolet Small Block Gen 1 engines. If you're building a pro-street or bracket racing machine, this kit gives you the foundation for improved performance. It's engineered to work with a good intake manifold, headers, appropriate gearing, and a torque converter rated at 3300 RPM or higher to really let this cam breathe.

Inside this kit, you'll find the camshaft itself, a set of matching solid lifters, assembly lube to get everything started right, and decals. This kit is specifically for engines that use a flat tappet camshaft setup. It's important to verify your engine's configuration, as many later model Small Blocks, especially from 1985 onward, came with factory roller camshafts. This kit will not work with those roller blocks, nor will it fit any LS-based engines. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the fifth cam journal is required.

This kit is a solid option for enthusiasts looking to extract more power from their classic Chevrolet V8. It's a significant upgrade over stock, but remember that to get the most out of it, you'll need to ensure the rest of your engine and drivetrain are set up to support its aggressive profile. This includes proper tuning and supporting modifications.
