Holley has been manufacturing fuel systems of all shapes and sizes since 1903. In fact, over 250,000,000 carburetors have been produced over the years for everything from Henry Ford's original Model A to the baddest factory muscle cars ever to roll out of Detroit. Did you know that Holley supplied over half the carburetors in WWII including not just automobiles, but PT Boats and airplanes? It's true. No company knows fuel systems like Holley.

Today, Holley carburetors continue to be a dominant force in high performance and racing, winning more races than all others combined. Holley carbs have powered every NASCAR® Sprint® Cup Series team and every winning NHRA® Pro Stock team since the 1960s and every weekend still today. 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. That engine was put onto a three wheeled vehicle that hit an impressive 30 MPH. That led to motorized bicycles, a four wheeled automobile called the Holley Motorette and the birth of the Holley Motor Company.

In 1903, at the urging of Henry Ford, the Holley brothers entered the carburetor business and became industry leaders in fuel system technology. In 2003 Holley was recognized as one of four original suppliers still selling to Ford after 100 years. The company business continued to expand through the World War I and World War II era. It could be said that Holley directly helped win World War II as about half the carburetors used bore the Holley name. Holley fuel systems were on everything from variable venturi carburetors on the DC-3 airplane, Packard powered PT boats to the B-25s used in Jimmy Doolittle's air raid on Tokyo.

Following the war Holley concentrated on keeping up with the requirements of automobile manufacturers who, in turn, were trying to keep up with the demands of a car-hungry public. Holley also began supplying repair parts to service stations and garages. War scrapped airplane belly tanks were finding their way to the salt flats and carburetors like the famous Holley 94s were powering many of these racers.

The 1950's saw the introduction of the Holley Model 4150 4-barrel on the 1957 T-bird. It was the beginning of the modular Holley 4-barrel as we know it today. It was the first true performance carburetor and became standard equipment on many high performance automobiles. The 1960's were huge for the hot rod industry, and Holley, as the Model 4150 became original equipment on the baddest factory muscle cars ever to come out of Detroit. It powered cars like the popular Z28 Camaros, Big Block Chevelles, Boss Mustangs and Shelby Cobras to name a few. This era also saw the introduction of the awesome Holley three deuce multi carb set-ups on 427 (Tri Power) Corvettes and 440 (Six Pack) Mopars. If it was a serious car it had to have a Holley.

An American icon was also born in the '60s as the Holley Double Pumper® rolled off the line. The world famous Holley Dominator® also made its debut in 1968, developed specifically for NASCAR® racing. The 1970s saw Holley's continuation of dominance in racing with nearly every factory NHRA® Super Stock/Pro Stock racer running Holley's. That hasn't changed and in fact, Holley carbs have powered more drag racers than all other carbs combined, still today. The early 70's also saw the introduction of the world famous Holley "Blue" electric fuel pump which also become the most dominant fuel pump in drag racing history. It too powers tens-of-thousands of racers and street enthusiasts still today. This era also saw the introduction of Holley aluminum intake manifolds, including the once popular Z-Series developed in conjunction with Zora Arkus-Duntov.

Holley entered the 1980's positioned as the only carburetor manufacturer to offer entire fuel systems from intakes to fuel pumps. Holley continued its dominance in nearly all forms of racing powering all winning NHRA Pro Stock racers and once again all NASCAR® Sprint® Cup Series teams of the day. The '80s also saw Holley's entrance into the fuel injection market where original equipment EFI components and analog Pro-Jection® retro-fit fuel injection systems for carbureted cars were introduced.

In the 1990's Holley continued its new product introductions. The wildly popular HP Pro Series race ready carburetors were introduced and have become the standard in racing ever since. The, still popular, SysteMAX® engine kits were introduced with matched cylinder heads, intakes and cams. The Dominator also evolved in the '90s into the HP Dominator, huge billet electric fuel pumps were introduced, and retrofit EFI kits evolved into digital Pro-Jection 4D and 4Di.

In addition to products from its other brands, so far in the new millennium Holley has introduced the popular Street Avenger, Truck Avenger, Street HP and Ultra HP carburetors as well as billet mechanical fuel pumps. Holley's EFI systems evolved with the Commander 950® ECU and now includes a full line of billet aluminum high flow EFI throttle bodies, multipoint EFI kits and Stealth RamT EFI kits.

Just recently in 2007, the Holley 3310 carburetor was inducted into the Inaugural Hot Rod Magazine Speed Parts Hall of Fame as one of the top ten influential speed parts of all time. Holley looks forward to continuing its influence on the performance aftermarket for another 100 years. We hope you do too!

In 2010, it's the new generation of intelligent EFI systems. See below: Click here for catalog.
