COMP Cams Cam & Lifter Kit CS Nx284H-13

If you're building a Pro Street Chevrolet Small Block for serious street performance, this COMP Cams Cam and Lifter Kit is a solid choice. This kit features the Nx284H hydraulic flat tappet camshaft, designed to work well with multi-stage nitrous kits or a 671 blower, and it's built for engines needing a 2800+ stall torque converter. It's a popular upgrade for a wide range of classic Chevrolet Gen 1 Small Block engines, including popular displacements like the 350 and 400 cubic inch variants.

This kit includes the camshaft, a set of matching hydraulic lifters, assembly lube to get you started right, and decals for your engine bay. The camshaft profile offers 240 degrees of intake duration and 253 degrees of exhaust duration at .050 inch lift, providing a noticeable bump in performance for street applications that see regular use. It’s important to confirm your specific engine uses a flat tappet camshaft, as many later model Small Blocks (especially from 1985 onward) transitioned to factory roller camshafts, which are not compatible with this kit.
