COMP Cams Camshaft CBVI XM308HR-12

This product is the COMP Cams Xtreme Marine hydraulic roller camshaft, part number CBVI XM308HR-12. It's designed for Chevrolet Big Block GEN VI engines, fitting a range of trucks and vans like the 1996-2000 Chevrolet C2500 Suburban and GMC Savana 3500. This camshaft is a key component for improving engine performance, especially in applications like jet boats running B impellers, or for bracket racing where consistent power delivery is crucial.

The Xtreme Marine camshaft features a 254/260 degree duration at 0.050 inch lift, with a 112-degree lobe separation angle. This profile is well-suited for engines with a compression ratio of 10:1 or higher, helping to maximize power output. As a hydraulic roller camshaft, it offers reduced friction compared to flat tappet designs, contributing to better efficiency and potentially longer engine life. Its design is optimized for the demands of marine racing and drag strip performance, providing a noticeable improvement in throttle response and overall power band.

When installing this camshaft, ensure your engine meets the compression ratio requirements and is set up for performance use. This camshaft is intended for modified engines and is not CARB approved, meaning it cannot be shipped to California. It's a solid option for those looking to extract more power from their Big Block Chevrolet engine for specialized racing applications.
