Product Details

The COMP Cams CL12-564-4 Nitrous HP Camshaft and Lifter Kit is specifically engineered for small block Chevrolet engines running nitrous oxide systems. This complete kit delivers aggressive performance with a 230/244 duration split designed to maximize power under nitrous activation while maintaining excellent throttle response and drivability.

Camshaft Specifications:

  • Advertised Duration: 280°/292° intake/exhaust
  • Duration at .050": 230°/244° intake/exhaust
  • Valve Lift: .510"/.540" intake/exhaust (with 1.5 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for reliable operation
  • RPM Range: 2,000-6,200 RPM

Complete Kit Includes:

  • High-performance hydraulic flat tappet camshaft
  • 16 premium hydraulic lifters
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This camshaft profile is optimized for street/strip applications with nitrous oxide injection systems ranging from 100-250 HP shots. The aggressive exhaust duration helps purge cylinders efficiently under boost, while the tighter intake lobe maintains cylinder pressure for strong naturally aspirated performance. Ideal for use with aftermarket cylinder heads, headers, and a 2,500+ RPM stall converter. Requires valve spring upgrade for proper valve control at high RPM.
