Product Details

The COMP Cams Xtreme Marine camshaft is specifically engineered for marine applications in Chevrolet small block engines. This hydraulic flat tappet camshaft delivers a performance-oriented profile with 234/244 degrees of advertised duration, providing increased power and torque across the RPM range while maintaining reliability in demanding marine environments.

Key Features:

  • Hydraulic flat tappet design for smooth, quiet operation and low maintenance
  • 234° intake / 244° exhaust advertised duration for strong mid-range power
  • Marine-specific grind optimized for propeller loads and continuous-duty operation
  • Precision-ground on COMP Cams' CNC equipment for consistent lobe profiles
  • Compatible with stock valve springs and components in most applications
  • Manufactured from premium-grade materials for corrosion resistance

The Xtreme Marine series is designed to deliver enhanced performance without sacrificing the durability required for marine use. This camshaft provides excellent throttle response and increased power output compared to stock profiles, making it ideal for ski boats, cruisers, and other recreational marine vessels. The hydraulic flat tappet design ensures reliable operation with minimal adjustment requirements.

good customer service. answered my questions promptly and professionally.

Great website. Placed my order very quickly. Super easy to navigate. Looking forward to getting my order.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

fast shipping, lowest prices.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.
