Those were not "Muscle Cars" unless there was at least a 390 under the hood. Preferably a 427 or 428 to be a real muscle car. The line was a 389ci or bigger engine with a intermediate body or smaller. Pontiac started it all with a 389 Tri Power 64 GTO. And they ended it too with the 455 Super Duty Trans Am.View attachment 74717
Post a pic of your favorite muscle car. I’ve always liked the mid-60’s Ford Mustangs. The fastbacks are cool too.
PS - I don't know how to post a picture but if I did.. It would be a 69 Camaro Z28.
