Product Details

The COMP Cams 12-840-14 is a high-performance solid roller camshaft specifically designed for open wheel modified racing applications with traction control systems. This aggressive camshaft features a unique 4/7 cylinder swap configuration that optimizes power delivery and traction management in dirt track and asphalt modified racing.

Key Specifications:

  • Advertised Duration: 256°/261° intake/exhaust
  • Solid roller design for maximum valve control and durability
  • 4/7 cylinder firing order swap for enhanced traction control
  • Engineered specifically for small block Chevy engines
  • Designed for open wheel modified racing applications

Performance Features:

  • Optimized lobe profiles deliver aggressive power characteristics suited for oval track racing
  • 4/7 swap configuration creates intentional power imbalance to aid in traction management on dirt and asphalt surfaces
  • Solid roller construction eliminates valve float at high RPM and provides superior durability under extreme racing conditions
  • Split duration design (256°/261°) fine-tunes exhaust scavenging and power delivery

This camshaft requires compatible solid roller lifters, heavy-duty valve springs, and pushrods (sold separately). Professional installation and proper valvetrain setup are essential for optimal performance and engine longevity. Intended for dedicated racing applications with traction control systems.
