Ford 351c&m-400m Cam 268H (Hyd)

The COMP CAMS Ford 351C&M-400M 268H Hydraulic Cam (Part #32-221-3) is a high-energy hydraulic flat tappet camshaft engineered for Ford Cleveland and Modified engine platforms. This cam delivers 0.494 inches of lift on both intake and exhaust sides with a 268-degree duration specification and 110-degree lobe separation angle, making it a popular choice for street and street/strip Ford engine builds seeking broad powerband characteristics.

The 268-degree duration and 0.494-inch lift profile produces effective torque rise between 1500 and 5500 RPM, a range that suits daily-driven and moderate performance applications where drivability remains a priority. The hydraulic flat tappet design uses self-adjusting lifter technology, eliminating the need for manual valve lash adjustment and reducing complexity during installation. High-energy cam profiles rely on quality valve springs, rocker arms, and pushrods to perform reliably, so proper supporting components are essential for longevity and consistent operation across the intended RPM band.

This camshaft suits engine rebuilds and upgrades where builders prioritize versatile performance without extreme valve train demands. The 268H specification sits in the middle range of COMP CAMS' Ford Cleveland and Modified catalog, offering more aggressive characteristics than stock profiles while remaining compatible with factory or quality reproduction valve train hardware. Ford 351C, 351M, and 400M engine swaps and restorations represent the core audience for this cam, particularly those seeking a balance between streetability and performance gains over original equipment specifications.
