Product Details

The COMP Cams 11-737-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines (396-454 cubic inches). This aggressive profile delivers maximum power output at high RPM ranges, making it ideal for serious competition vehicles where all-out performance is the priority.

Camshaft Specifications:

  • Duration: 281° intake / 296° exhaust
  • Solid roller design for maximum lift and valve control
  • Optimized for drag racing and high-RPM applications
  • Designed for Chevrolet Big Block 396, 402, 427, and 454 engines
  • Requires solid roller lifters, high-ratio rocker arms, and heavy-duty valve springs (sold separately)

Performance Characteristics:

  • Wide lobe separation angle provides strong cylinder filling and power delivery
  • Aggressive ramp rates for quick valve actuation
  • Produces maximum horsepower in the upper RPM range
  • Rough idle with significant lope—not recommended for street-driven vehicles

This camshaft requires supporting modifications including a high-flow intake system, headers, upgraded valve train components, and proper engine tuning. Professional installation and break-in procedures are strongly recommended. Due to the aggressive nature of this profile, this cam is best suited for dedicated race engines with limited street use.
