COMP Cams Camshaft Kit C43 266H-R12

When you're looking to get more out of your Chevrolet 4.3L V6, this K-Kit from COMP Cams is a complete package designed to improve your engine's performance. This kit includes the C43 266H-R12 hydraulic roller camshaft, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a new timing chain set to ensure proper synchronization, plus assembly lube to help with installation. It's designed to work with throttle body and sequential port injection systems when using an aftermarket chip, offering a noticeable boost in low-end and mid-range power.

This kit is built around a hydraulic roller camshaft, which generally offers less friction and better performance compared to flat tappet designs. The camshaft itself has a 210 intake and 215 exhaust duration at .050 inch lift, making it a good choice for improving the torque curve of your 4.3L V6. It's intended for use with OE roller camshaft applications and is specifically tuned for engines with throttle body or sequential port injection, especially when paired with an aftermarket computer chip. This combination aims to provide a solid improvement in responsiveness and pulling power where you'll feel it most often.

This COMP Cams K-Kit is a comprehensive solution for upgrading your 4.3L V6, fitting a wide range of Chevrolet and GMC vehicles from the late 80s through the early 2000s, including popular models like the Chevrolet S10, GMC Sonoma, and Chevrolet Astro vans. Everything you need for the camshaft and valvetrain upgrade is included, from the core camshaft and lifters to the smaller components like valve locks and seals, along with the necessary timing set and assembly lube. Just remember, this kit is not CARB approved and cannot be shipped to California.
