This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern. If you have a spreadbore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.

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 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. This carb is universal and will work on any engine that has a square bore intake manifold and can use 600CFM but it is not a direct replacement for any OE carb Factory Refurbished Carburetors have limited availability. Holley Factory Refurbished FR-80457S are warranted for a period of 1 Year from date of sale for defects in material and workmanship. Any defective items will be repaired or replaced at Holley's discretion.
