Product Details

The COMP Cams 11-741-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet big block engines ranging from 396 to 454 cubic inches. This aggressive camshaft features a 281/300 duration profile designed to deliver maximum power in the upper RPM range where drag racing engines spend most of their time.

Key Specifications:

  • Intake Duration: 281 degrees
  • Exhaust Duration: 300 degrees
  • Solid roller design for maximum lift capability and reduced friction
  • Optimized lobe profiles for drag racing performance
  • Compatible with Chevrolet big block engines (396, 402, 427, 454 CID)

Performance Characteristics:

  • Aggressive duration profile delivers peak power at high RPM
  • Solid roller construction eliminates hydraulic bleed-down for consistent performance
  • Designed for engines with aftermarket cylinder heads, headers, and intake systems
  • Requires solid roller lifters, heavy-duty valve springs, and supporting valvetrain components
  • Best suited for dedicated race applications with manual transmission

This camshaft is intended for serious drag racing builds where idle quality and street manners are not a concern. Professional installation and proper valvetrain setup are essential to achieve optimal performance and reliability. Valve-to-piston clearance must be verified before installation.
