COMP Cams Camshaft Kit CS XR282HR-10

This COMP Cams Xtreme Energy camshaft kit (SK12-432-8) is designed for Chevrolet Gen 1 Small Block engines. When you open the box, you'll find the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set, assembly lube to help with installation, and decals for your engine bay. This kit is a popular choice for builders looking to significantly upgrade their street machine's performance, but it does require supporting modifications like an intake manifold, headers, a torque converter with at least a 2500 RPM stall speed, and appropriate rear-end gearing to perform at its best. Expect a mildly rough idle, which is characteristic of a more aggressive camshaft profile.

The camshaft features a 230-degree intake duration and a 236-degree exhaust duration, with a 110-degree lobe separation angle. This specific grind is intended for engines like the 350, 400, and other displacement variations within the Gen 1 Small Block family. It's important to verify your engine's original setup, as GM gradually introduced roller camshafts from the mid-80s onward. While many performance-oriented vehicles like Camaros and Corvettes received them early, some trucks and SUVs retained flat tappet cams well into the 90s. A quick check by removing the intake manifold or timing cover will confirm if your block is factory roller-ready or requires a flat tappet camshaft. This kit is not compatible with LT1/LT4 engines or any LS-based V8s.

For optimal performance and longevity, ensure all supporting components are up to the task. The included assembly lube is crucial for protecting the camshaft lobes and lifters during initial startup. Remember that this kit is not CARB approved and cannot be shipped to California. If you're working on a 1955-1957 Chevrolet 265 engine, confirm if the 5th cam journal has an oiling groove; if not, contact us for specific guidance.
