Product Details

The COMP Cams 08-301-8 Nitrous HP hydraulic roller camshaft is specifically engineered for small block Chevrolet engines equipped with factory roller lifters and running nitrous oxide systems. This performance camshaft delivers a potent combination of strong mid-range torque and aggressive top-end power, making it ideal for street/strip applications where nitrous is used for maximum acceleration.

Camshaft Specifications:

  • Advertised Duration: 270°/278° intake/exhaust
  • Duration at .050": 224°/236° intake/exhaust
  • Valve Lift (with 1.5 ratio rockers): .510"/.540" intake/exhaust
  • Lobe Separation Angle: 112°
  • Hydraulic roller design for OE roller blocks
  • Recommended RPM Range: 1,500-6,200

Key Features:

  • Optimized lobe profiles designed specifically for nitrous oxide applications
  • Works with factory hydraulic roller lifters and blocks (1987-up SBC)
  • Provides excellent throttle response and street manners
  • Aggressive exhaust duration for improved cylinder scavenging under nitrous
  • Compatible with factory or aftermarket fuel injection and carburetion

This camshaft works best with 9.5:1 to 10.5:1 compression ratio, upgraded valve springs, and a 2,200-2,800 RPM stall converter for automatic transmissions. The tight 112° LSA helps maintain strong vacuum for power brakes while still delivering the cylinder pressure needed for effective nitrous usage. Ideal for engines ranging from 350 to 383 cubic inches running 100-150 horsepower nitrous systems.
