Product Details

The COMP Cams 12-652-20 is a high-performance solid flat tappet camshaft designed specifically for oval track racing applications in Chevrolet small block engines. This camshaft features a nitride finish for enhanced durability and wear resistance under demanding racing conditions.

Camshaft Specifications:

  • Advertised Duration: 248° intake / 250° exhaust
  • Solid flat tappet design for precise valve control
  • Nitride coating for superior hardness and extended service life
  • Engineered for oval track racing performance
  • Optimized for Chevrolet small block V8 engines (262-400 cu in)

This camshaft is designed to deliver strong mid-range torque and excellent throttle response for circle track competition. The nitride treatment provides a hard, wear-resistant surface that reduces friction and extends camshaft life in high-stress racing environments. Requires use with solid/mechanical lifters, appropriate valve springs, and proper break-in procedures.
