Product Details

The COMP Cams 12-564-4 is a high-performance hydraulic flat tappet camshaft specifically engineered for Chevrolet small block engines running nitrous oxide systems. This camshaft delivers aggressive performance with 230 degrees of intake duration and 244 degrees of exhaust duration at 0.050" lift, providing the ideal power characteristics for nitrous-assisted applications.

Key Specifications:

  • Advertised Duration: 280° Intake / 294° Exhaust
  • Duration at 0.050": 230° Intake / 244° Exhaust
  • Valve Lift: 0.510" Intake / 0.540" Exhaust (with 1.5 ratio rocker arms)
  • Lobe Separation Angle: 110 degrees
  • Hydraulic flat tappet design for reliable performance
  • Optimized for nitrous oxide applications

Performance Characteristics:

  • Designed to handle the extreme cylinder pressures generated by nitrous systems
  • Broader exhaust duration helps evacuate combustion gases efficiently under boosted conditions
  • Tight lobe separation angle maximizes cylinder pressure and torque
  • Ideal RPM range: 1,800-6,000 RPM
  • Recommended for street/strip applications with nitrous oxide injection

This camshaft is designed for use with stock or aftermarket hydraulic lifters and requires appropriate valve springs to handle the lift specifications. Professional installation and proper break-in procedures are essential for optimal performance and longevity.
