Product Details

If you're looking to get more grunt out of your GM 4.3L V6, especially in the low-end and mid-range where you use it most, this COMP Cams Magnum computer-controlled camshaft is a solid option. This hydraulic roller camshaft is designed specifically for balance shaft-equipped 4.3L engines found in a wide range of GM vehicles from 1992 through 2014, including popular models like the Chevrolet S10, GMC Sonoma, and Chevrolet Express vans. It's built to work with throttle body and sequential port injection systems when paired with an aftermarket engine control chip, making it a practical upgrade for many older GM trucks and SUVs.

This camshaft features a 210/215 degree intake/exhaust duration at .050 lift, which is a popular grind for improving torque and responsiveness without sacrificing too much drivability. Because it's a hydraulic roller design, you'll benefit from reduced friction and wear compared to flat tappet cams, leading to a longer lifespan and more consistent performance. Keep in mind that this camshaft requires an adjustable valve train setup to ensure proper geometry and tuning for optimal performance and engine health. The specific timing cover on balance shaft-equipped 4.3L engines is taller than the non-balance shaft versions, so ensure you have the correct cover for installation.

When installing this camshaft, it's important to follow the manufacturer's instructions carefully, especially regarding the valve train setup. This camshaft is a significant upgrade for your engine's breathing capabilities, and it's designed to make a noticeable difference in how your vehicle performs during everyday driving and towing. Please note that this part is not CARB approved and cannot be shipped to California.
