The COMP Cams 08-412-8 Xtreme Energy hydraulic roller camshaft is designed specifically for small block Chevrolet engines equipped with OE roller cam components. This performance camshaft delivers a notable increase in power and torque over stock, making it an excellent choice for street/strip applications and weekend warriors looking for aggressive throttle response without sacrificing driveability.

Camshaft Specifications:

  • Advertised Duration: 268°/274° (Intake/Exhaust)
  • Duration @ .050": 212°/218° (Intake/Exhaust)
  • Valve Lift: .447"/.463" (Intake/Exhaust) with 1.5 rocker ratio
  • Lobe Separation Angle: 112°
  • Recommended RPM Range: 1,500-5,800 RPM
  • Hydraulic roller design works with OE roller lifters and components

Key Features:

  • Xtreme Energy lobe profiles optimize performance across the RPM range
  • Drop-in replacement for OE roller cam equipped SBC engines (1987-up)
  • Produces excellent low-end and mid-range torque with strong top-end power
  • Maintains good vacuum for power brakes and accessories
  • Compatible with stock torque converters and rear gear ratios
  • Aggressive idle quality with a noticeable performance sound

This camshaft is ideal for street performance builds, mild bracket racing, and towing applications where improved power delivery is desired.

Requires proper degreeing during installation for optimal performance.
