COMP Cams Camshaft Kit CS 264HR-12

This is the COMP Cams CS 264HR-12 Hydraulic Roller Camshaft Kit, designed for 1987 and newer Chevrolet 305 and 350 small block engines that came with factory roller camshafts. It's a complete package aimed at providing mild performance improvements, particularly for Tuned Port Injection (TPI) applications, and it really helps build strong power from the low end up through the mid-range. Because this kit changes your engine's breathing characteristics, it requires custom tuning to get the most out of it and ensure everything runs smoothly.

When you open the box, you'll find everything you need to get this camshaft installed and running. The kit includes the camshaft itself, a set of hydraulic roller lifters, the correct valve springs, retainers, and valve locks to match. You also get valve stem seals, a timing chain set for precise valve timing, and assembly lube to help during installation. COMP Cams even includes decals and detailed instructions to guide you through the process. This is a well-built kit that bundles all the essential components for a camshaft upgrade, saving you the hassle of sourcing each part individually.

This kit is a solid option for owners looking to wake up their engine's performance without going to an extreme setup. It's engineered to work with the factory roller valvetrain found in many Gen 1 small block Chevys, making it a direct fit for a wide range of vehicles from the late 80s through the 90s, including models like the Chevrolet Camaro, Corvette, and C/K series trucks. Keep in mind that due to emissions regulations, this part is not CARB approved and cannot be shipped to California.
