Product Details

The COMP Cams 11-411-8 Nitrous HP hydraulic roller camshaft is specifically engineered for nitrous oxide applications in Chevrolet Big Block engines (396-454 cubic inches). This performance camshaft delivers aggressive power characteristics optimized for engines running nitrous systems, with a focus on excellent mid-range to top-end performance.

Camshaft Specifications:

  • Advertised Duration: 280°/288° intake/exhaust
  • Duration at .050": 230°/242° intake/exhaust
  • Valve Lift: .525"/.540" intake/exhaust (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized lobe profiles for nitrous oxide injection systems

Key Features:

  • Designed specifically for nitrous-assisted big block Chevy engines
  • Hydraulic roller technology eliminates the need for break-in procedures
  • Wider lobe separation angle helps manage cylinder pressure with nitrous
  • Provides strong power delivery from 2,500 to 6,500 RPM
  • Compatible with stock or aftermarket hydraulic roller lifters and valve train components
  • Requires aftermarket valve springs for proper operation

This camshaft is ideal for street/strip applications where nitrous oxide is used for additional power. The hydraulic roller design provides reliability and performance without the maintenance requirements of solid roller camshafts. Best suited for engines with compression ratios between 9.5:1 and 11:1, aftermarket cylinder heads, and a quality ignition system.
