Product Details

The COMP Cams 12-504-5 is a high-performance solid flat tappet camshaft designed specifically for Chevrolet small block engines. This tight lash camshaft features an aggressive 254/254 duration profile that delivers excellent mid-range to high-RPM power, making it ideal for street/strip applications and performance builds that demand strong top-end horsepower.

Key Specifications:

  • Duration at .050": 254° Intake / 254° Exhaust
  • Valve Lift: .480" Intake / .480" Exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Tight lash design for reduced valvetrain noise and improved performance
  • Solid flat tappet design for durability and adjustability

Performance Characteristics:

  • RPM Range: 1,500-6,000 RPM
  • Strong mid-range to top-end power delivery
  • Produces a noticeable performance idle with good vacuum
  • Excellent choice for manual transmission applications
  • Requires performance valve springs and proper break-in procedure

This camshaft is compatible with stock or aftermarket cylinder heads and works well with mild compression ratios. Professional installation is recommended, along with upgraded valve springs, pushrods, and proper engine assembly lubrication. A quality break-in oil containing ZDDP additives is essential for proper cam and lifter break-in with flat tappet camshafts.
