COMP Cams Camshaft Kit CS Nx276HR-13

This is the COMP Cams Camshaft Kit CS Nx276HR-13, designed for Chevrolet Gen 1 Small Block engines. It's a hydraulic roller camshaft kit that's a popular choice for street machines looking to add a significant nitrous system or a small supercharger. If you're building a performance engine for a classic Chevy, like a Camaro, Corvette, or a C10 pickup, this kit can really wake it up.

The kit includes the camshaft itself, a set of lifters, a timing chain set, assembly lube, decals, and instructions, so you have the core components needed for the swap. The camshaft features a 224-degree intake and 236-degree exhaust duration with a .550-inch intake and .560-inch exhaust lift, making it suitable for builds that will see higher RPMs and require a good amount of airflow. It's recommended to pair this with a torque converter with at least a 2200 RPM stall speed and lower gearing to take full advantage of its performance potential.

It's important to note that this kit is designed for engines with a flat tappet camshaft setup. While GM started phasing in roller camshafts in the mid-80s, many trucks and SUVs continued with flat tappet cams into the mid-90s. You'll need to remove the intake manifold or timing cover to confirm if your specific engine has a factory roller setup, as this kit is not compatible with those. Also, this kit is not CARB approved and cannot be shipped to California.
