Product Details

The COMP Cams K12-210-2 High Energy/Marine K-Kit is a complete camshaft upgrade package for Chevrolet Gen I small block engines. Grind number 268H, this hydraulic flat tappet camshaft is engineered for strong street performance and serves double duty as the largest recommended camshaft for inboard and outboard marine applications — making it an excellent choice for ski boats, economy builds, and light performance use on the water.

This cam delivers a broad, usable powerband across a 1,500–5,500 RPM operating range, with a slightly choppy idle character that signals its performance intent. It is designed to work with mostly stock components including stock rockers, intake and exhaust manifolds, carburetors, and torque converters — no major supporting modifications required. The camshaft is C.A.R.B. compliant (E.O. #D-279-3, #D-279-5, #D-279-6) and 50-state legal for 1987 and earlier carbureted V8 small block Chevrolet applications.
