COMP Cams Camshaft Kit C43 270AH-R10

This COMP Cams K-Kit gives you everything you need to swap in a new camshaft and related components for your Chevrolet 4.3L V6. Inside this box, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, assembly lube, and even some decals and instructions to help you out. It's designed for computer-controlled vehicles and is a popular choice when you're looking to get more out of your engine's breathing.

The C43 270AH-R10 camshaft is a hydraulic roller type, which generally means less friction and more consistent valve lift compared to flat tappet designs. It's tuned for strong performance in the mid-range and top end of the RPM band, making it a great option for drivers who want a noticeable improvement in acceleration and power when they push the engine. To really take advantage of what this cam offers, you'll likely need to pair it with an aftermarket computer chip, a less restrictive exhaust system, and a torque converter with a slightly higher stall speed. This kit is built for a range of Chevrolet and GMC vehicles from the late 80s through the late 90s, including popular models like the S10, Blazer, and Astro vans.

When installing this camshaft kit, remember that it's intended for vehicles originally equipped with an OE roller camshaft. Because this is a performance upgrade, it's important to consult the included instructions for proper installation procedures and any specific requirements for your vehicle's computer and exhaust system. This kit is not approved for sale in California due to emissions regulations.
