COMP Cams Camshaft Kit CB X4 270H-11

This is the COMP Cams Xtreme 4x4 Camshaft Kit, designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts. If you're looking to get more out of your big block, this kit is a solid option. It includes the camshaft itself, a set of lifters, a timing chain set, assembly lube, decals, and instructions, so you have the core components needed for the job.

The X4 270H-11 camshaft has a 226-degree intake and 234-degree exhaust duration at .050 lift, with a 111-degree lobe separation angle. This profile is well-suited for trucks and muscle cars, especially when paired with an improved intake manifold, headers, and rear gears in the 3.55 to 3.90 range. A torque converter with at least a 2000 RPM stall speed is recommended to take full advantage of the camshaft's performance potential. This kit is built with COMP Cams' reputation for well-made engine components, aiming to provide a noticeable improvement in your engine's power band.

This kit fits a wide range of Chevrolet vehicles from the late 1960s through the mid-1980s, including popular models like the C10 Pickup, Camaro, and Impala. Make sure to check the full fitment list to confirm it's right for your specific application.
