COMP Cams Camshaft Kit CS 252H

This is the COMP Cams High Energy CS 252H Camshaft Kit, part number K12-205-2. It's designed for Chevrolet Small Block engines, specifically those with flat tappet camshafts, covering displacements from 327 to 400 cubic inches. This kit is a popular choice for builders looking for strong torque and improved mileage, all while maintaining a smooth idle, making it well-suited for vehicles with higher axle ratios.

When you choose this K-Kit, you're getting a complete package to handle the camshaft upgrade. It includes the CS 252H camshaft itself, a set of hydraulic flat tappet lifters, valve springs, retainers, valve locks, and valve stem seals. You'll also find a timing chain set to ensure proper synchronization, assembly lube for the flat tappet components, and helpful instructions. This comprehensive approach means you have most of what you need to get the job done right, ensuring the new camshaft operates as intended for optimal performance.

This kit is a solid option for a wide range of Chevrolet applications, including many trucks and SUVs that retained flat tappet designs well into the 1990s. It's important to verify your specific engine uses a flat tappet camshaft, as many later model Small Blocks, particularly from 1985 onward, transitioned to factory roller camshafts. Removing the intake manifold or timing cover is the surest way to confirm. If your engine is a 1955-1957 265ci, ensure it has the necessary oiling groove on the fifth cam journal.
