Product Details

The COMP Cams 12-871-11 is a high-performance hydraulic roller camshaft designed specifically for drag racing applications in Chevrolet small block engines. This aggressive camshaft features a 260/270 duration split, providing excellent mid-range to top-end power for competitive racing.

Key Specifications:

  • Duration at .050": 260° intake / 270° exhaust
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized for drag racing and high-performance street/strip applications
  • Designed for Chevrolet small block V8 engines (262-400 ci)
  • Delivers strong acceleration and high RPM power

Performance Features:

  • Hydraulic roller technology eliminates the need for break-in procedures
  • Aggressive lobe profiles maximize airflow and cylinder filling
  • Exhaust duration bias helps scavenge cylinders for improved power
  • Compatible with factory hydraulic roller blocks (1987-up) or retrofit roller lifter conversions
  • Requires appropriate valve springs, retainers, and pushrods (sold separately)

This camshaft is ideal for racers seeking maximum performance in drag racing applications where strong mid-range torque and top-end horsepower are critical. Best suited for engines with aftermarket cylinder heads, intake manifolds, and exhaust systems. Recommended RPM range: 2,000-6,500 RPM.
