COMP Cams Camshaft FF XM 278H-12

This COMP Cams Xtreme Marine camshaft is designed for Ford 429 and 460 Big Block engines. You get the camshaft itself, ready to be installed into your engine. It's a hydraulic flat tappet camshaft, meaning it uses hydraulic lifters to maintain zero valve lash, which generally makes for a quieter and more comfortable operation compared to solid lifters. This particular grind is well-suited for jet boat applications, especially those using an 'A' impeller, and it really likes to breathe, so good manifolds and headers are recommended to get the most out of it.

The 234/244 duration at 0.050 inch lift is a notable specification, offering a good balance for performance in marine environments. This camshaft fits a wide range of Ford and Lincoln vehicles from the late 60s through the mid-90s, including popular models like the Ford F-250 and Lincoln Continental. Its design aims to improve engine breathing and power output, particularly in applications where exhaust flow is not restricted.
