Product Details

The COMP Cams 11-613-5 is a high-performance solid flat tappet camshaft engineered specifically for drag racing applications in Chevrolet big block engines from 396 to 454 cubic inches. This aggressive cam delivers serious power gains with its 270/280 duration profile, making it ideal for dedicated race vehicles where maximum acceleration and quarter-mile performance are the priority.

Key Specifications:

  • Advertised Duration: 270° intake / 280° exhaust
  • Duration @ .050": 230° intake / 236° exhaust
  • Valve Lift: .510" intake / .520" exhaust (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Solid flat tappet design for high-RPM durability
  • Optimized for 2500-6800 RPM operating range

Performance Features:

  • Aggressive profile delivers strong mid-range to top-end power
  • Designed for manual transmission drag race applications
  • Works best with 10:1 or higher compression ratio
  • Requires aftermarket valve springs and performance valve train components
  • Compatible with flat tappet lifters (sold separately)

This camshaft requires a complete valve train upgrade including appropriate valve springs, retainers, lifters, and pushrods rated for the increased lift and duration. Professional installation and tuning are recommended to achieve optimal performance. Not intended for street use due to rough idle and reduced vacuum characteristics.
