COMP Cams Camshaft Kit CS XR264HR-12

This is the COMP Cams CS XR264HR-12 Hydraulic Roller Camshaft Kit, part number SK08-416-8. It's designed for '87 and later GEN 1 Chevrolet 305 and 350 small block engines that came with a factory roller camshaft. This kit is a popular choice for owners looking to wake up their engine with a noticeable bump in power and torque, especially in applications like classic trucks, muscle cars, and marine use where the 'Xtreme Marine' designation hints at its robust design.

Inside this kit, you'll find the XR264HR camshaft itself, which features a 212-degree intake and 218-degree exhaust duration at .050 lift, along with a 112-degree lobe separation angle. This profile is known for delivering a strong torque curve and improved horsepower without being overly radical for street or marine applications. COMP Cams also includes a set of hydraulic roller lifters, a timing chain set to ensure precise valve timing, assembly lube to get everything started right, and even some decals and instructions to help guide you through the installation. The camshaft is a direct replacement for OE roller camshafts, meaning it fits right into the factory provisions without needing extensive modifications, though always refer to the manufacturer's instructions for specific details.

This kit is a comprehensive package for anyone undertaking an engine rebuild or upgrade on compatible small block Chevys. It covers a wide range of vehicles from the late 80s through the mid-90s, including popular models like the Chevrolet C1500, Camaro, and Caprice. While it's not CARB approved and cannot be shipped to California, it represents a solid option for enhancing the performance of your classic Chevy engine.
