Product Details

The COMP Cams 12-872-11 is a high-performance hydraulic roller camshaft specifically engineered for drag racing applications in Chevrolet small block engines. This aggressive camshaft delivers exceptional power and torque characteristics optimized for maximum quarter-mile performance.

Key Specifications:

  • Advertised Duration: 267°/275° (intake/exhaust)
  • Camshaft Type: Hydraulic roller
  • Application: Chevrolet small block V8 engines
  • Design: Drag race focused performance profile
  • Construction: Premium billet core with precision-ground lobes

Performance Features:

  • Hydraulic roller design provides excellent durability and reduced friction compared to flat tappet cams
  • Aggressive lift and duration profile delivers strong mid-range to top-end power
  • Split-pattern design with longer exhaust duration optimizes cylinder scavenging
  • Ideal for bracket racing and strip-dedicated small block Chevy applications
  • Requires compatible hydraulic roller lifters, pushrods, and valve springs (sold separately)

This camshaft is designed for engines with upgraded valve train components and is best suited for race-only applications where idle quality and low-speed drivability are not primary concerns. Professional installation and proper break-in procedures are recommended to ensure optimal performance and longevity.
