Product Details

The COMP Cams 20-721-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chrysler small block engines (273-360 cubic inch). This aggressive camshaft delivers maximum horsepower and torque for competitive racing environments where every tenth of a second counts.

Camshaft Specifications:

  • Duration: 274° intake / 279° exhaust (advertised duration)
  • Design: Solid roller lifter design for superior valve control and higher RPM capability
  • Application: Chrysler small block V8 engines (273, 318, 340, 360 cubic inch)
  • Intended Use: Drag racing and competition applications

Performance Features:

  • Solid roller design eliminates lifter flex and provides precise valve timing at high RPM
  • Aggressive profile optimized for maximum power output in racing applications
  • Increased duration provides extended valve opening time for improved cylinder filling
  • Requires compatible solid roller lifters, appropriate valve springs, and supporting valvetrain components

This camshaft is designed for dedicated race engines with supporting modifications including high-compression pistons, performance cylinder heads, and racing valve springs. Professional installation and proper valvetrain setup are essential for optimal performance and engine longevity. Not recommended for street-driven vehicles due to aggressive profile and idle characteristics.
