Product Details

The COMP Cams 01-456-8 Xtreme Marine hydraulic roller camshaft is specifically engineered for marine applications using Chevrolet Big Block Gen VI engines. This performance camshaft delivers excellent low-end torque and mid-range power, making it ideal for inboard and stern drive marine installations where throttle response and reliable performance are critical.

Key Specifications:

  • Advertised Duration: 242°/248° (intake/exhaust)
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized lift profile for marine power delivery characteristics
  • Designed for Big Block Chevrolet Gen VI marine engines
  • Corrosion-resistant materials suitable for marine environments

Features and Benefits:

  • Enhanced throttle response for better boat handling and acceleration
  • Broad power band ideal for varying load conditions and RPM ranges
  • Hydraulic roller technology reduces valve train wear and maintenance
  • Marine-specific grind accounts for the unique demands of marine propulsion
  • Compatible with factory fuel injection and carburetor setups

This camshaft is part of COMP Cams' Xtreme Marine series, which is specifically developed to withstand the harsh operating conditions of marine engines including moisture exposure, constant load variations, and extended periods at sustained RPM. The hydraulic roller design provides quieter operation compared to flat tappet cams while offering improved durability and performance. Requires compatible hydraulic roller lifters, timing set, and proper valvetrain components (sold separately).
