Product Details

The COMP Cams 12-609-20 is a high-performance solid flat tappet camshaft designed for Chevrolet Small Block engines in extreme racing applications including drag racing, tractor pulling, mud racing, and off-road competition. This aggressive cam delivers maximum power for race-only applications where idle quality and street manners are not a concern.

Key Specifications:

  • Advertised Duration: 250°/260° intake/exhaust
  • Solid flat tappet design for maximum reliability under extreme conditions
  • Engineered specifically for Chevrolet Small Block V8 engines
  • Optimized for race fuel and high compression ratios
  • Requires solid lifters, performance valve springs, and pushrods (sold separately)

Performance Characteristics:

  • Aggressive lobe profiles for maximum horsepower and torque
  • Designed for high RPM operation and quick acceleration
  • Split duration design with longer exhaust duration for improved cylinder scavenging
  • Best suited for manual transmission and deep gear ratios
  • Requires professional installation and valve train setup

This camshaft is intended for competition use only and is not legal for street use in emissions-controlled vehicles. Professional engine building experience and proper valve train components are essential for successful installation and operation.
