Chris' Object of Automotive Desire - 10/12

By 1973, all the real muscle cars were dead - except for the Pontiac Firebird Trans Am SD-455. The SD stood for Super Duty, and the 455 stood for 455 cubic inches of heart-pumping V-8 power - real, brutish V-8 power in an era that double or tripled the output of its contemporaries.

With 0-60 runs in the low 5-second range despite slippery tires, the SD-455 would be a supercar even by today's standards. The SD-455 was the lone beacon of light as Detroit's proud performance tradition began to circle the bowl of the toilet of the 1970s.
