Overview
Holley HP™ carburetors have been the standard in racing carburetors for nearly two decades. Powering the biggest names in NASCAR to the Saturday night racer, HP carburetors are the perfect choice for all types of motorsports.
Classic HP carburetors are available from 390 to 1000 CFM and feature a contoured venturii inlet for balanced air flow, screw in air bleeds for precision tuning capabilities, high flow metering blocks and Dominator style fuel bowls which allow pluming from either side for ease of installation.
Holley HP carburetors are the standard for square bore race carburetors. Race-Ready out of the box!
This is an official Holley Performance Factory Refurbished Carburetor listing. 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.
