Product Details

The COMP Cams 12-318-4 High Energy Marine camshaft is specifically designed for small block Chevrolet marine applications, delivering proven performance with corrosion-resistant construction. This hydraulic flat tappet camshaft features 222° intake and 226° exhaust duration, making it an ideal choice for improving throttle response and mid-range power in marine engines.

Key Features:

  • Marine-specific design with enhanced corrosion resistance for saltwater and freshwater environments
  • 222° intake / 226° exhaor duration for improved torque and throttle response
  • Hydraulic flat tappet design for quiet operation and minimal maintenance
  • Engineered for Chevrolet small block V8 engines (262-400 cubic inches)
  • High Energy grind profile optimized for street and recreational marine use
  • Compatible with stock valve springs and components in most applications

This camshaft is part of COMP Cams' proven High Energy series, offering a balanced combination of performance and reliability. The marine-grade materials and coatings provide superior protection against the harsh operating conditions found in boat applications, while the moderate lift and duration specifications ensure broad power delivery without sacrificing low-end torque.
