I was watching speed channel last night and they annointed the 64 GTO as bing the first muscle car. Their definition of a muscle car was a production car with a big motor and poformance options.
I'm not here to argue, but rather;submit the following cars for discussion....In 1957 ..cadillac had a V8 with 2 4 barrels...chevy had a fuel injection system in 57....in 58,,chevy had a 348 with tri power... although the caddy in 57 was a 2x4 barrel setup..it was a luxury car...with balls...the 57 chevy with the injection system was unique. Who wanted a luxury car in 58 with tri power. I submit...even though I am a mopar guy...that chevy...in 1958 through 63 started the whole thing with the 348 tri powr and then making the "SS" an option with engines as big as 409. Mopar stated in with the wedge in 62...ford had a 406 tri power in 62 or 63. (not here to argue....supportive info more than welcome) I believe the SS chevy was the first true muscle car
