Product Details

The COMP Cams CL11-414-8 Nitrous HP hydraulic roller camshaft and lifter kit is specifically engineered for big block Chevrolet engines (396-454 cubic inches) running nitrous oxide systems. This complete kit delivers aggressive performance with a 242/254 duration split designed to maximize power under nitrous activation while maintaining strong naturally aspirated characteristics.

Camshaft Specifications:

  • Advertised Duration: 282°/294° intake/exhaust
  • Duration at .050": 242°/254° intake/exhaust
  • Valve Lift: .563"/.580" intake/exhaust (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized for nitrous oxide applications with proper fuel system

Complete Kit Includes:

  • Hydraulic roller camshaft
  • Premium hydraulic roller lifters (16)
  • Assembly lube for proper break-in
  • COMP Cams decals
  • Detailed installation instructions

This camshaft delivers a lopey idle with excellent throttle response and is ideal for street/strip vehicles with 9.5:1 or higher compression, aftermarket cylinder heads, and a 2,800-3,400 RPM stall converter. The hydraulic roller design eliminates the need for break-in procedures required with flat tappet cams while providing superior valvetrain stability at high RPM. Power range is optimized from 2,500 to 6,500 RPM, making this an excellent choice for nitrous-equipped street machines and bracket racing applications.
