Product Details

The COMP Cams 11-733-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines (396-454 cubic inches). This aggressive camshaft delivers maximum power in the upper RPM range, making it ideal for serious bracket racing and competitive drag strip use.

Camshaft Specifications:

  • Intake Duration: 282 degrees
  • Exhaust Duration: 298 degrees
  • Solid roller lifter design for high-RPM stability and performance
  • Optimized lobe profiles for maximum horsepower and torque
  • Compatible with Chevrolet Big Block 396, 402, 427, and 454 engines

Performance Characteristics:

  • Designed for dedicated drag racing and competition use
  • Produces strong top-end power with aggressive valve timing
  • Requires aftermarket valve springs, pushrods, and roller lifters
  • Intended for engines with modified cylinder heads and intake systems
  • Not recommended for street-driven vehicles due to rough idle and poor low-RPM manners

This camshaft requires professional installation and proper break-in procedures. A complete valvetrain upgrade including roller lifters, hardened pushrods, dual valve springs, and retainers is mandatory for proper operation and reliability.
