COMP Cams Cam & Lifter Kit CB Nx294H

This is the COMP Cams Nitrous HP hydraulic flat tappet camshaft and lifter kit, part number CL11-572-4. It's built for Chevrolet Big Block engines, specifically the 396 through 454 cubic inch displacements that originally came with flat tappet camshafts. This kit is intended for race-only applications, particularly those using an 871 blower, and requires supporting modifications like good cylinder heads, an appropriate intake manifold, and a rear gear ratio, along with a torque converter with a stall speed of 3500 RPM or higher.

The camshaft features a nitrous-optimized profile with intake and exhaust durations of 250 and 264 degrees respectively, at .050 inch lift. This design aims to maximize power output when used with forced induction and nitrous oxide. The kit includes the camshaft, lifters, assembly lube, decals, and installation instructions, providing a well-rounded package for your engine build. COMP Cams is known for producing well-built valvetrain components, and this kit is a solid option for serious racers looking to extract maximum performance from their big block Chevrolet.
