Product Details

The faster intake valve opening on this COMP Cams CS Nx284H-13 camshaft helps increase engine vacuum and improve throttle response. This camshaft is designed for Chevrolet Small Block engines from 262 to 400 cubic inches, fitting a wide range of vehicles from 1958 through 2002, including many classic GM cars and trucks like the Chevrolet Camaro, Caprice, and C10. It's a solid choice for Pro Street applications, especially those running multi-stage nitrous kits or a 671 blower, and works well with a 2800+ stall torque converter.

COMP Cams engineered this camshaft with special intake closing ramps that shut the valve sooner. This design creates more cylinder pressure and torque without causing excessive valve train noise. The faster ramps also achieve maximum lift quicker, increasing the area under the lift curve for maximum horsepower. Smoother exhaust designs are incorporated to help purge spent gases more effectively from the combustion chamber, further boosting horsepower.

This camshaft is suitable for use with either a carburetor or a tunable fuel injection system. For engines built from 1985 and newer, it's important to confirm whether your block is a factory roller or flat tappet design, as this camshaft is a hydraulic flat tappet type and does not fit factory roller small blocks. If you're unsure, removing the intake or timing cover will help you determine compatibility.
