There’s much more behind the name on the building and we take a look by the numbers.

Holley Performance Products, based in Bowling Green, Kentucky, has a long and rich history in automotive performance since 1896. Originally based out of Michigan, the company was one of the major producers of carburetors, being supplied as standard equipment on many Detroit-built automobiles.

During the heyday of the musclecar era, they manufactured carburetors for V8 street and racing applications such as the Holley “double pumper”. Holley-style carburetors have powered every NASCAR Sprint Cup team and every NHRA Pro–Stock champion for four decades.

Holley’s product range has expanded to include fuel injection, performance fuel pumps, intake manifolds, cylinder heads and engine dress–up products for street performance, race and marine applications. Among the company’s owned divisions are brand names Nitrous Oxide Systems (NOS), Weiand, FlowTech, Earls and Hooker Headers.
