List of United States Automotive, Motorcycle, Boat, Dealers, Service Stations
This generally refers to American mid-size cars with large engines built mostly from 1964 to 1972. The first true American muscle car was the 1964 Pontiac GTO, with a 325 hp 389 4 bbl engine, and an optional 389 tri-power producing 348 hp. Although every American car manufacturer, including AMC with its venerable AMX 390, produced muscle cars during this time period, probably the last true big-block muscle cars of this genre were also Pontiacs: the extremely fast SD 455 Trans Am was produced in 1973 and 1974 in limited numbers.
