COMP Cams Camshaft Kit CB X4 278H-11

This COMP Cams camshaft kit gives you everything you need to get a solid power upgrade for your Chevrolet Big Block engine. Inside this kit, you'll find the Xtreme 4x4 234/244 hydraulic flat tappet camshaft, a set of lifters, a timing chain set, assembly lube, decals, and instructions. This kit is designed for Chevrolet GEN IV 396-454 Big Block engines that originally came with flat tappet camshafts, covering a wide range of vehicles like the Chevrolet Impala, Chevelle, and Camaro from the late 60s through the mid-70s.

The X4 278H-11 camshaft is built to deliver good top-end power, making it a great choice if you're looking to improve performance on the highway or at the track. To really make this camshaft shine, you'll want to pair it with a good intake manifold, headers, and appropriate rear-end gears. The manufacturer suggests using this cam with around 9.5:1 compression and a torque converter with a 2500 RPM stall speed or higher to get the most out of its performance potential.
