COMP Cams Camshaft Kit CB Nx273HR-13

This is the COMP Cams Camshaft Kit CB Nx273HR-13, part number SK11-409-8. It's a hydraulic roller camshaft kit designed specifically for Chevrolet Big Block engines, including the 396, 427, and 454 cubic inch displacements. This kit is intended for street machines that are running a nitrous oxide system, typically with at least a 125 horsepower shot, a torque converter with a 2200+ RPM stall speed, and lower rear-end gears. It's a well-built package that aims to improve performance for these specific applications.

Inside this kit, you'll find everything you need to get started on your camshaft upgrade. It includes the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set for proper valvetrain synchronization, and assembly lube to ensure everything goes together smoothly and lasts. COMP Cams is known for its performance valvetrain components, and this kit reflects that expertise. The camshaft features a 224-degree intake duration and a 236-degree exhaust duration, with a 113-degree lobe separation angle, making it suitable for naturally aspirated power as well as nitrous-assisted builds. This is a significant upgrade over a stock flat tappet camshaft, offering improved airflow and power potential.

This kit is designed to fit a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, such as the Chevrolet Chevelle, Camaro, and Impala from the late 1960s through the mid-1970s, as well as various C/K series trucks and Suburbans. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures to get the most out of this performance camshaft kit.
