Overview

This is an official Holley Performance Factory Refurbished Carburetor. Factory Refurbished carbs are NOT old worn-out carbs that have been rebuilt. They are carbs that were returned under warranty. When these carbs are returned, we check them out and most of the time there is nothing wrong with them. Generally, they were simply adjusted out of working range by the installer. Since these carbs may show signs of a previous installation, our policy is not to sell them as new. Rather than scrapping them, we are making them directly available to the public. Not only does this help us control the costs of our new carbs, it allows you to get a great deal on a like-new carburetor! Factory Refurbished carbs have undergone a thorough inspection. Any damaged parts that would effect performance have been replaced and the carbs are solvent cleaned before being wet-flow-tested on Holley's state-of-the-art flow benches allowing them to be recalibrated to new carb specs. Factory Refurbished carbs may have scratches, blemishes, and other visual flaws from previous installation. Factory Refurbished Carburetors have limited availability. The 0-80583-1 carburetor shares the hugely successful features of the original 4412 carburetor, but with changes aimed directly at circle track cars. The choke assembly has been removed for unobstructed airflow, utilizes the HP metering block , 30cc accelerator pump, welded throttle lever, screw in air bleeds and stainless throttle plates, plus it has been specially calibrated for circle track racing use. It comes out of the box ready to run with less modifying and less tuning at the track!

Features:

  • Gold Dichromate finish for corrosion resistance and classic Holley looks
  • Calibrated specifically for circle track use
  • No choke for unobstructed airflow
  • 30cc accelerator pump for additional fuel under initial acceleration
  • HP metering block for improved fuel flow
  • Screw in air bleeds for precision tuning capabilities
  • Welded throttle lever
  • Power valve blow-out protection
  • 100% wet-flow tested by Holley technicians to assure it arrives ready to run!
