Product Details

The COMP Cams 11-726-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines from 396 to 454 cubic inches. This aggressive camshaft delivers maximum power and torque for competitive racing environments where raw performance is paramount.

Key Specifications:

  • Advertised Duration: 284° intake / 308° exhaust
  • Solid roller lifter design for maximum valve control and high-RPM stability
  • Optimized lobe profiles for drag racing power bands
  • Precision ground from premium billet cores for consistency and durability
  • Compatible with Chevrolet Big Block 396, 402, 427, and 454 cubic inch engines

Performance Characteristics:

  • Aggressive split-duration design favors exhaust scavenging for forced induction or nitrous applications
  • Designed for engines with aftermarket cylinder heads, headers, and high-compression pistons
  • Requires solid roller lifters, compatible valve springs, and pushrods (sold separately)
  • Best suited for dedicated race vehicles with manual or high-stall automatic transmissions

This camshaft is designed for serious drag racing builds and requires supporting modifications including a performance valvetrain, upgraded valve springs with appropriate seat pressure, and proper break-in procedures for solid roller applications. Professional installation and valve lash adjustment are recommended for optimal performance and engine longevity.
