COMP Cams Camshaft Kit CS 280R

This is the COMP Cams CS 280R Solid Roller Camshaft Kit, part number K12-702-8. It's designed for Chevrolet Small Block GEN 1 engines, offering a significant performance upgrade for street/strip applications. This kit is built for those looking for a noticeable power increase and a more aggressive engine note, featuring a camshaft with a choppy idle that works best with a 2500+ RPM stall converter and headers. It's intended for builds with approximately 9.5:1 compression.

When you choose this kit, you're getting a complete package to handle the camshaft upgrade. It includes the solid roller camshaft itself, lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure a proper installation and optimal performance, the kit also comes with a timing chain set, assembly lube (for flat tappet applications), decals, and detailed instructions. This comprehensive approach means you have most of the critical components needed for the job, reducing the need to source individual parts separately.

This kit fits a wide range of Chevrolet Small Block GEN 1 engines, including popular displacements like the 262, 283, 305, 327, 350, and 400. However, it's important to verify your specific engine's configuration. This kit is not compatible with LT1/LT4 engines or factory roller small blocks produced from 1985 onward, as GM gradually transitioned to roller camshafts during that period. To confirm, you may need to remove the intake manifold or timing cover to check if your block uses a flat tappet or factory roller setup. It also does not fit any LS-based engines.
