Holley's kits provide the necessary brackets and hardware for installation, allowing you to select supplemental accessories and components based on your preferences and budget, whether sourced from a salvage yard, local auto parts store, GM parts dealer, or Holley.

A Fitment And Required Components Guide assists you in locating and sourcing components, offering additional notes and helpful hints. Three simple steps guide you through the process. Step one is to determine your belt alignment based on your crank pulley position on the engine. Step two is to choose the Holley accessory drive brackets needed (A/C, Alt & P/S or both). Step three is to identify the Holley installation kit your setup requires to align your accessories with your crank pulley position. An application-specific installation kit (part # 21-1, 21-2, or 21-3) is REQUIRED for most applications.
