Ah yes, 1973. The year the automotive world in America changed. with regulation came pain and loss of power, and few men managed to retain the raw brutal horsepower of the pre- regulation era. The last of the breed, like the 1972 Mach-1 Mustang, the 1971 Plymouth Hemi-Cuda, and the 1973 Pontiac 455SD Firebird.
So opponaughts, it's important for us to remember the year 1973.
