Edelbrock Performance Camshafts- Cam Card Locator

Performance Camshafts and Lifter Kits by Edelbrock
Edelbrock camshafts are matched to Edelbrock Total Power Package components for proven performance, taking the guesswork out of camshaft selection. They are compatible with OEM or Edelbrock hydraulic roller tappets which reduce friction, virtually eliminate break-in problems, and permit higher valve velocities for increased performance.
