There were "Muscle Cars" before the GTO. One example would be the 1963 Dodge Polara with a 426 Wedge engine and Cross Ram manifolds. There was also the 1962 Dodge Dart with the 413 etc..
Chrysler missed out for having the "1st Muscle Car" title, because GM had a better marketing group.
Pictured below is the 1963 Dodge Polara.
