Product Details

The COMP Cams 12-501-5 is a high-performance solid flat tappet camshaft designed specifically for Chevrolet small block engines. This tight lash camshaft delivers 242 degrees of advertised intake duration and 246 degrees of advertised exhaust duration, providing an aggressive profile ideal for street/strip applications and performance street builds.

Key Features:

  • Solid flat tappet design for maximum durability and performance
  • 242/246 advertised duration provides strong mid-range to top-end power
  • Tight lash specification reduces valvetrain noise and maintains consistent valve timing
  • Engineered specifically for Chevrolet small block V8 engines (262-400 cubic inches)
  • Precision ground from premium core materials for extended service life
  • Ideal for engines with performance cylinder heads, intake manifolds, and headers

This camshaft is designed for enthusiasts seeking noticeable performance gains with a choppy idle and strong acceleration. The solid lifter design requires periodic valve lash adjustment but offers superior rpm capability and valvetrain stability compared to hydraulic camshafts. Best suited for engines with upgraded valvetrain components and 9.5:1 or higher compression ratios.
