What is the main benefit of a hydraulic roller camshaft like this one?

Hydraulic roller camshafts generally offer improved durability and allow for more aggressive lobe designs compared to older flat tappet camshafts. This can lead to increased engine performance and a longer lifespan for the camshaft itself.

What kind of performance gains can I expect with this camshaft?

This camshaft is designed for bracket racing and performance use, particularly in marine applications like jet boats. You can expect an improved powerband and increased horsepower compared to a stock camshaft, especially in the mid-to-upper RPM range.

What other parts might I need when installing this camshaft?

When upgrading to a performance camshaft, it's recommended to ensure your valve springs, lifters, and pushrods are compatible with the camshaft's specifications for lift and duration. It's also wise to inspect your timing set and oil pump.

Product Details

If you're building a performance marine engine, especially for bracket racing or a jet boat with an A or B impeller, this COMP Cams Xtreme Marine camshaft is a solid choice. It's designed to work with Chevrolet Big Block GEN VI engines, specifically those found in 1996-2000 era trucks and vans like the Chevrolet C/K series and GMC C/K series. This camshaft is all about getting more out of your big block, offering an updated profile for improved performance over stock.

This camshaft features a hydraulic roller design, which is a step up from older flat tappet designs. Roller cams generally offer better durability and allow for more aggressive lobe profiles, leading to increased lift and duration. The specs here, 242 degrees of intake duration and 248 degrees of exhaust duration at .050 lift, are tuned for a good balance of power and drivability in performance marine applications. The 112-degree lobe separation angle is also key, helping to create a strong powerband that's well-suited for the demands of racing or high-performance boating.

When installing a camshaft like this, it's important to have the right supporting components. While this camshaft is designed to fit a range of Chevrolet and GMC Big Block Gen VI engines from 1996-2000, it's always a good idea to check your specific engine's requirements. Ensure your valve springs, lifters, and pushrods are compatible with the increased lift and duration this camshaft offers. This is a significant upgrade for anyone looking to extract more power from their big block marine engine.
