COMP Cams Cam & Lifter Kit CB Nx273HR

If you're building a street machine that's ready for a serious nitrous boost, this COMP Cams Cam & Lifter Kit is designed to get you there. This kit is specifically for Chevrolet Big Block engines originally equipped with flat tappet camshafts, like those found in classic models such as the Chevrolet Chevelle, Camaro, and Impala from the late 60s through the mid-70s. It's engineered to work with a 125+ horsepower nitrous kit, a torque converter with a 2200+ RPM stall speed, and lower rear gear ratios, making it a solid choice for performance-oriented builds.

At the heart of this kit is the CB Nx273HR camshaft, a hydraulic roller design that offers improved performance over traditional flat tappet setups. Hydraulic roller cams generally provide better durability and allow for more aggressive lobe profiles, which translates to more power. This specific camshaft has a 224-degree intake and 236-degree exhaust duration at .050 inch lift, and a .550 inch intake and .560 inch exhaust lift, designed to work in harmony with the included lifters. The kit comes complete with everything you need to get started: the camshaft, high-quality hydraulic roller lifters, assembly lube to ensure proper break-in, and decals for that finishing touch.

This is a comprehensive package for anyone looking to significantly increase the horsepower of their Big Block Chevrolet. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure the longevity and performance of your new camshaft and lifter setup.
