Product Details

This COMP Cams Xtreme Marine camshaft features a 218-degree intake and 224-degree exhaust duration at .050 lift, a common specification for hydraulic roller camshafts designed for improved performance while maintaining a good idle. This particular grind, the CBVI XM270HR-12, is intended for Chevrolet Big Block GEN VI engines, specifically those found in inboard/outboard pleasure boats. The design aims to provide a smooth, manageable idle suitable for cruising and recreational use, making it a popular choice for engine rebuilds where a noticeable upgrade is desired without sacrificing drivability.

Built with a hydraulic roller design, this camshaft reduces friction compared to flat tappet designs, allowing for more aggressive lobe profiles that can increase airflow into and out of the cylinders. This translates to better power output and throttle response. The camshaft is constructed from durable materials to withstand the demands of marine applications. It is designed to fit a range of Chevrolet and GMC trucks and Suburbans from the mid-to-late 1990s, including models like the C2500 Suburban and K3500, offering a significant performance improvement for these big block engines.

When considering this camshaft, remember that it is specifically designed for marine applications and may not be suitable for all automotive uses, especially in emissions-controlled vehicles. It is not CARB approved and cannot be shipped to California. Ensure you consult with a professional or refer to COMP Cams' detailed installation guides to confirm compatibility with your specific engine build and to understand any other components, such as valve springs or pushrods, that may be required for optimal performance and longevity.
