The late 1970s were a difficult time to be a performance car enthusiast. Following the OPEC oil embargo and the introduction of much more restrictive emissions requirements, American gearheads watched their favorite muscle cars wither away. The roaring big-block V8s of the early '70s were either discontinued or choked down to horsepower figures that seemed almost insulting. The EPA even blocked dealers from offering special engine-swapped models like the famous 427ci Camaros from Yenko, Baldwin, and Nickey. However, one Arizona-based Pontiac dealer found a workaround to produce a significantly faster 1977-80 Trans Am called the Macho Trans Am.
