Notable Holley carbs include the Holley 2100, also known as the '94' or AA-1, introduced on the '34 Ford and variously marked as a Holley or with a Ford script. This one served on flathead V8's for many years, as well as on early Y-blocks as the 2110 version. Another interesting series were the concentric carbs also known as 'Teapots' for their unusual suspended float bowl. These started with the model 1901 2 barrel on the '49 Merc, evolved into the 4 barrel model 4000 on '55-57 TBirds and other cars, and continued until 1975 on IHC trucks. The biggest hit for Holley was the modular series of carburetors, which debuted in 1957, and are the well-known 2 and 4 barrel Holleys still being sold today.
