Holley Street Avenger Performance 570 CFM Four Barrel Carburetor

Part #: 0-81570

In 1896, Bradford, Pennsylvania was like any other small town - except it was home to the Holley family. It was during this time that George and Earl took an interest in motorcycle racing.

 This invention of the Runabout shifted the brothers' interest from motorcycles to the emerging automotive industry. George and Earl founded the Holley Motor Company and introduced the Motorette in 1903, which inspired Henry Ford to request Holley to produce a carburetor for his Model T, called the Iron Pot. It quickly became an automotive success and became standard on Ford vehicles as well as the curved-dash Oldsmobile.

The change in direction influenced George and Earl Holley to relocate their headquarters from Bradford to Detroit, Michigan. Late in 1907, the doors opened to their first plant in the Detroit area. Thanks to the booming automotive industry and a diversified industrial approach (due to World War I), the company changed its name to The Holley Carburetor Company in January of 1918.

In 1994, Holley underwent major changes. The original equipment division was sold to Borg-Warner, which led to the relocation of Holley Performance Replacement Parts' headquarters to Bowling Green, KY. At this time, the company's name became Holley Performance Products.

Over the next several years the Holley name was placed on Hirel Technologies Fuel Injection, Weiand Automotive Industries, Lunati, Hooker Headers, Flowtech Exhaust, Earl's Performance Plumbing, and NOS. These acquisitions have allowed customers to purchase any performance product, all made with the Holley Performance approach to quality.
