Product Details

The COMP Cams 08-418-8 Xtreme Marine camshaft is specifically engineered for small block Chevrolet marine applications using OE roller blocks. This hydraulic roller cam delivers 224/230 degrees of advertised duration, providing enhanced performance and durability for inboard and sterndrive engines.

Key Features:

  • Designed specifically for marine environments with corrosion-resistant materials
  • 224/230 advertised duration optimized for marine torque characteristics
  • Hydraulic roller design for reduced friction and improved reliability
  • Compatible with OE roller small block Chevy blocks (1987-up)
  • Provides strong low-end and mid-range torque for marine applications
