Product Details

COMP Cams is well-known for performance engine components, and their Magnum hydraulic roller camshafts are a popular choice for those looking to improve their engine's breathing. This particular camshaft, the CV6B 270HR-10, is designed for Chevrolet 4.3L (262 cubic inch) V6 engines that are equipped with balance shafts. It's intended to provide mild street performance with a slightly noticeable idle, making it a good match for stock torque converters when you've already upgraded your intake and headers.

This camshaft features a 215/215 duration at .050 lift, which is a common specification for a mild performance upgrade. It's important to note that this camshaft requires an adjustable valve train and is intended for carbureted applications. The balance shaft equipped 4.3L engines have a distinct timing cover that is taller than the non-balance shaft versions, so be sure to identify your specific engine setup. This camshaft is designed to fit a wide range of GM vehicles from 1992 through 2014, including popular models like the Chevrolet S10, GMC Sonoma, and Chevrolet Astro vans.

When installing this camshaft, remember that it requires an adjustable valve train setup. This is a significant upgrade for your engine, and while it offers improved performance, it's designed to work with existing stock converters when paired with aftermarket intake and header upgrades. Always refer to the manufacturer's installation instructions for specific details regarding valve train setup and any other required components.
