Product Details

The COMP Cams SK11-445-8 Xtreme Marine camshaft kit is a complete hydraulic roller cam package designed specifically for Chevrolet big block engines (396-454 ci). This SK-Kit (Small Kit) provides everything needed for a camshaft upgrade in marine and high-moisture applications where corrosion resistance is critical.

Camshaft Specifications:

  • Intake Duration: 218 degrees
  • Exhaust Duration: 224 degrees
  • Hydraulic roller design for reduced friction and increased durability
  • Marine-grade materials with enhanced corrosion protection
  • Engineered for Chevrolet big block 396-454 cubic inch engines

Complete Kit Includes:

  • Camshaft with marine-grade finish
  • Hydraulic roller lifters (16 pieces)
  • Timing chain set
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This Xtreme Marine camshaft is specifically engineered to withstand harsh marine environments where standard camshafts would quickly corrode. The hydraulic roller design provides smoother operation, reduced valve train wear, and improved performance compared to flat tappet designs. The 218/224 duration profile delivers strong mid-range torque and reliable power, making it ideal for marine applications where dependability is paramount.
