Product Details

This COMP Cams CS 252Ah-12 camshaft features a 206-degree intake and 212-degree exhaust duration at .050 lift, designed specifically for hydraulic flat tappet lifters. It's built for use in throttle body injection, crossfire, and TPI 305 and 350 engines, offering an improved performance profile over stock for these computer-controlled applications.

This camshaft is well-built for Chevy Gen 1 Small Blocks, covering a wide range of displacements from 262 to 400 cubic inches. While it's designed for engines with flat tappet lifters, it's important to verify your specific block's provisions, especially for 1985 and newer GM engines which may have come with roller lifters from the factory. If your block has the provisions for roller lifters and you desire a roller setup, COMP Cams offers specific hydraulic roller lifter install kits and camshafts.

This camshaft fits a wide variety of vehicles, including popular models like the Chevrolet Camaro, Caprice, and C10 trucks from the 1980s and early 1990s. Always confirm your engine's specific configuration, particularly regarding roller versus flat tappet lifters, before installation.
