Below is an abbreviated list of applications for the Mighty Demon Carburetor.


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 nearly every winning NHRA® Pro Stock team since the 1960s and every weekend still today.
