Product Details

The COMP Cams 12-502-5 is a high-performance solid flat tappet camshaft designed specifically for Chevrolet small block engines. This tight lash camshaft features a 250/254 duration split, providing excellent mid-range torque and upper RPM power for street performance and mild racing applications.

Key Specifications:

  • Advertised Duration: 278°/286° intake/exhaust
  • Duration at .050": 250°/254° intake/exhaust
  • Valve Lift: .454"/.480" intake/exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,800
  • Valve Lash: .016"/.018" intake/exhaust (hot)

Features and Benefits:

  • Tight lash design reduces valvetrain noise and allows for more aggressive lobe profiles
  • Solid flat tappet construction provides direct, responsive valve actuation
  • Ideal for street performance applications with manual transmissions
  • Works well with stock or mildly modified cylinder heads
  • Delivers strong throttle response and excellent driveability
  • Requires adjustable valve lash for proper installation and maintenance

This camshaft is best suited for small block Chevrolet engines in street-driven vehicles where improved performance and a more aggressive idle are desired while maintaining good street manners. Requires the use of break-in lubricant and proper valvetrain components including compatible valve springs, lifters, and pushrods.
