COMP Cams Camshaft C43 260H-R10

This COMP Cams C43 260H-R10 camshaft is a hydraulic roller upgrade designed for 1987 through 1998 GM 4.3L (262 cubic inch) V6 engines that do not have a balance shaft. You'll receive the camshaft itself, ready to be installed in your Chevrolet Astro, Blazer, S10, or GMC Sonoma, among many other compatible vehicles. This camshaft is intended as a performance upgrade over your stock unit, aiming to provide better mileage and a smooth idle, making it a solid choice for vans, pickups, and towing applications when paired with stock gear ratios and a stock torque converter.

The Magnum 206/206 designation refers to its intake and exhaust duration at 0.050 inch lift, indicating a mild performance profile that balances power gains with drivability. Because this is a hydraulic roller camshaft, it requires an adjustable valvetrain setup to ensure proper operation and longevity. This type of camshaft is known for its efficiency and ability to maintain a consistent idle, which is crucial for daily drivers and work vehicles. The design focuses on improving the engine's breathing without sacrificing the smooth operation you expect from a daily driver.

When installing this camshaft, remember that it's designed for carbureted applications and is not CARB approved, meaning it cannot be legally shipped to California. It's important to ensure your engine's timing cover is the correct type for a non-balance shaft 4.3L; the balance shaft version has a noticeably taller timing cover. This camshaft is a significant upgrade for your V6 engine, offering a noticeable improvement in performance and efficiency while maintaining a comfortable driving experience.
