Product Details

The COMP Cams SK12-564-4 Nitrous HP Small Kit is a complete performance camshaft package engineered specifically for Chevrolet Small Block engines running nitrous oxide systems of 125+ HP or medium-sized superchargers.

  • Exhaust valve lift: 0.501 inches
  • Duration at 0.050" lift: 230° intake / 244° exhaust
  • Advertised duration: 274° intake / 292° exhaust
  • Lobe separation angle: 113°

  • Hydraulic flat tappet lifters
  • Timing chain set
  • Assembly lube
  • Installation instructions
  • COMP Cams decals

The unique design of this Nitrous HP camshaft maximizes the effectiveness of nitrous systems through optimized intake lobe profiles that allow cylinders to fill more completely for enhanced combustion. The exhaust lobes feature spread timing to reduce overlap and ensure maximum scavenging of the combustion chamber, delivering increased power from your nitrous system without sacrificing throttle response or low-end torque. This camshaft is best suited for applications with a 2,500+ RPM stall converter and will produce a rough, aggressive idle. CARB exempt for racing and off-road competition vehicles only.
