  • Duration @ .050": 231°/231° intake/exhaust
  • Valve Lift (with 1.5 ratio rockers): .462"/.462" intake/exhaust
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for quiet, maintenance-free operation
  • Ideal RPM range: 1,500-5,500 RPM

Performance Characteristics:

  • Produces a noticeable performance idle with good vacuum
  • Broad torque curve for excellent throttle response
  • Compatible with stock torque converters and rear axle ratios
  • Works with stock valve springs and components
  • No computer reprogramming required for non-EFI applications

This camshaft is designed for engines with stock to mildly modified cylinder heads, headers or performance exhaust, and intake manifolds. The symmetrical duration and lift specs provide balanced power delivery across the RPM range. COMP Cams manufactures this camshaft from premium materials with precision lobe profiles to ensure consistent performance and durability.
