Did you know that Holley supplied over half the carburetors in WWII including not just automobiles, but PT Boats and airplanes? It all began in the late 1800s with two brothers from Bradford, PA, George and Earl Holley - teenage boys who learned how to make patterns and castings so they could build a one cylinder engine. Now, Holley manufactures high performance carburetors, manifolds, superchargers, water pumps, throttle body fuel injection and fuel pumps for street and race applications. In producing these parts, Holley prides itself in utilizing the latest technology in a lean environment to provide the highest quality parts at the best value to the customer.
