Product Details
If you're looking to get more mid-range power out of your classic Chevrolet small block engine, this COMP Cams Camshaft Kit is a solid option. This kit is designed for Gen 1 Small Block Chevys, including popular displacements like the 350, 400, and 327, and it's built to work with your stock torque converter for a straightforward upgrade. It aims to deliver a good performance increase, especially in the mid-range where you'll feel it most during everyday driving and acceleration.
This isn't just a camshaft; it's a complete K-Kit, meaning you get everything you need to get the job done right in one box. Inside, you'll find the XR260HR-11 hydraulic roller camshaft itself, along with matching lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure your engine's timing is spot on, plus assembly lube and instructions to guide you through the installation. This comprehensive approach helps ensure proper function and longevity for your new valvetrain setup.
It's important to confirm your specific engine setup before ordering. This kit is intended for engines with flat tappet camshafts. If your 1985 or newer small block Chevrolet was factory-equipped with a roller camshaft, this kit will not be compatible. You can typically determine this by removing the intake manifold or timing cover. This kit fits a wide range of Chevrolet and GM vehicles from the 1980s and early 1990s, such as the Chevrolet C10, Camaro, and Caprice, among many others. Always refer to the detailed fitment information to ensure it's the right choice for your build.
