Product Details

The COMP Cams 12-648-5 is a high-performance solid flat tappet camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft delivers aggressive mid-range to top-end power characteristics ideal for circle track competition.

Camshaft Specifications:

  • Advertised Duration: 282°/288° (intake/exhaust)
  • Duration at .050": 240°/246° (intake/exhaust)
  • Valve Lift: .510"/.520" (intake/exhaust) with 1.5:1 rocker ratio
  • Lobe Separation Angle: 108°
  • Recommended RPM Range: 2,800-6,800 RPM
  • Solid (mechanical) flat tappet design

Key Features:

  • Engineered specifically for oval track and circle track racing applications
  • Aggressive cam profile optimized for sustained high-RPM operation
  • Tight lobe separation angle for improved cylinder pressure and throttle response
  • Solid lifter design eliminates pump-up at high RPM for consistent valve control
  • Compatible with stock or aftermarket valve train components

This camshaft requires solid/mechanical lifters, appropriate valve springs, and periodic valve lash adjustment. Best suited for dedicated racing engines with adequate valve train components and supporting modifications. Not recommended for street use due to aggressive profile and maintenance requirements.
