Product Details

The COMP Cams Xtreme Marine camshaft is specifically engineered for marine applications running Chevrolet big block V8 engines from 396 to 454 cubic inches. This hydraulic flat tappet camshaft delivers a performance-oriented profile optimized for the unique demands of marine environments, including sustained high-load operation and resistance to corrosion.

Camshaft Specifications:

  • Advertised Duration: 268°/274° (Intake/Exhaust)
  • Duration @ .050": 218°/224° (Intake/Exhaust)
  • Valve Lift: .454"/.475" (Intake/Exhaust) with 1.7:1 rocker ratio
  • Lobe Separation Angle: 112°
  • Hydraulic flat tappet design for reliable, low-maintenance operation
  • RPM Range: 1,500-5,200 RPM (optimized for marine torque curve)

Key Features:

  • Xtreme Marine series design with enhanced corrosion resistance
  • Improved mid-range torque for better acceleration and load handling
  • Compatible with stock or aftermarket cylinder heads and intake manifolds
  • Requires hydraulic flat tappet lifters (not included)
  • Designed for use with marine-specific valve springs and valvetrain components

This camshaft provides a noticeable performance upgrade over stock profiles while maintaining the reliability and durability required for marine use. The broader powerband and increased torque output make it ideal for ski boats, runabouts, and cruisers that demand responsive throttle and strong pulling power.

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

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.

so far so good

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
