COMP Cams Camshaft GM Gen Iv LS2/LS3 AFM

This COMP Cams XFI AFM camshaft, part number 646-432-13, features a 216 intake and 228 exhaust duration at .050 inch lift, with a 113-degree lobe separation angle. This specific lobe profile is designed to work with GM's Active Fuel Management (AFM) system, allowing you to retain its functionality while still achieving notable performance gains. It's a hydraulic roller camshaft, which is standard for most modern GM LS engines, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs.

This camshaft is an excellent choice for modified applications, especially when paired with intake manifold and header upgrades. Owners of vehicles like the Pontiac G8, Chevrolet Caprice, or Cadillac Escalade with compatible LS engines can expect improved power output across a wider RPM range. The design aims to provide a significant performance increase over the stock camshaft, making it a popular upgrade for those looking to get more out of their LS-based engine. It's well-built for the demands of performance driving and is designed to be a direct replacement for your factory camshaft, simplifying the installation process.

When installing this camshaft, it's important to follow the manufacturer's recommended procedures, which typically involve replacing valve springs and potentially lifters to match the camshaft's specifications. While this camshaft is designed to work with AFM, it's crucial to ensure all related AFM components are in good working order. Please note that this part is not CARB approved and cannot be shipped to California.
