Product Details

COMP Cams is well-known for making performance engine parts, and this K-Kit is a prime example of their commitment to the Chevrolet Small Block V8. If you're looking to build a high-performance street engine that can handle a bit more power and has a noticeable rumble, this kit is designed to help you achieve that. It's built around their Magnum CS 280H-R10 hydraulic roller camshaft, which is a popular choice for those upgrading from older flat-tappet designs.

This isn't just a camshaft; it's a complete package to get your engine breathing better. Inside this kit, you'll find the camshaft itself, a set of hydraulic roller lifters designed to work with it, and all the necessary valve springs, retainers, and valve locks to match. COMP Cams also includes valve stem seals to ensure proper sealing, a timing chain set for accurate valve timing, and assembly lube to get everything started right. This kit is intended for a limited high-performance street application and works best with aftermarket intake manifolds, headers, a torque converter with at least a 2200 RPM stall speed, and rear-end gears in the 3.40 to 4.10 range. Expect a mild, rough idle that lets everyone know you mean business.

This kit fits a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350, 400, and 327. It's important to note that this kit is for engines that originally used a flat-tappet camshaft. If your engine was built from 1985 or later, especially in performance models like Camaros and Corvettes, it might have come with a factory roller camshaft from GM. You'll need to check your specific block to confirm if it's a factory roller or a flat-tappet design before installation. This kit is not compatible with LT1, LT4, or any LS-based engines.
