1973 Mustang General Information

The 1973 Mustang resembled the 1971 and 1972 Mustangs very closely. The front bumpers, front fenders and grille are slightly different.  However, if you look casually at the cars, the average person will not be able to distinguish one year from another.

Bumpers and bumper mountings were modified to meet the new federal crash standards.

Engine availability changed in 1973 because they no longer offered the 351 HO engine.  You could get the 351 4bbl adn 351 2bbl as an upgrade from the 302.

This was the last year for large and performance cars for about the next 20 years. The next performance car Ford will make will be in 1983 when they make a GT with a 4bbl carburetor.  The Lee Iacocca Mustang II made its debut in 74 and thereafter for the next 4 years.
