COMP Cams Camshaft Kit CS Nr276HR-113

This is the COMP Cams CS Nr276HR-113 hydraulic roller camshaft kit, designed for 1987 and newer General Motors small block V8 engines with factory roller camshafts, excluding LT-1 and LS1 variants. If you're looking to significantly increase the power output of your Chevrolet or Buick V8, especially when using nitrous oxide or a small supercharger, this kit is built to deliver. It's engineered to work well with lower gear ratios and a torque converter with a stall speed of 2200 RPM or higher, making it a popular choice for street/strip applications.

This complete kit includes everything you need to perform a camshaft upgrade. You get the camshaft itself, a set of hydraulic roller lifters, matching valve springs, retainers, valve locks, and valve stem seals. To ensure proper installation and timing, the kit also comes with a timing chain set and assembly lube. COMP Cams has included decals and detailed instructions to guide you through the process. This setup is intended to provide a substantial horsepower gain, often exceeding 125 horsepower when combined with other performance modifications like headers.

When installing this camshaft kit, remember that it's designed for engines that already have a factory roller camshaft setup. This means you'll be upgrading an existing roller system rather than converting from a flat tappet design. The specific camshaft profile, with its 224 degrees of intake duration and 236 degrees of exhaust duration at .050 inch lift, along with a 113-degree lobe separation angle, is tuned for optimal performance in the RPM range where forced induction or nitrous is most effective. Ensure your vehicle's exhaust system and fuel delivery can support the increased airflow and power.
