COMP Cams Camshaft Kit CB X4 278H-11

When you're looking to get the most out of your Chevrolet Big Block engine, this complete camshaft kit from COMP Cams is a solid option. Inside this box, you'll find everything you need to get the job done: the Xtreme 4x4 278H-11 hydraulic flat tappet camshaft itself, a set of lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, assembly lube, and even some decals and instructions. This kit is designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts, covering a wide range of vehicles like the 1967-1975 Chevrolet Impala, 1967-1973 Chevelle, and 1967-1974 Corvette.

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 for applications like drag racing or heavy-duty towing where you need the engine to breathe freely at higher RPMs. To really unlock its potential, COMP Cams recommends pairing it with a good intake manifold, headers, and appropriate rear-end gears. They also suggest using this kit with a 9.5:1 compression ratio and a torque converter with a stall speed of 2500 RPM or higher, which helps ensure the camshaft operates effectively in its intended power band.

This is a comprehensive kit designed to simplify your engine build. By including all the necessary valvetrain components and a timing set, it helps ensure proper installation and compatibility, saving you time and potential headaches sourcing individual parts. Remember that this kit is not CARB approved and cannot be shipped to California.
