Today on Past Gas: Where did the idea of the muscle car come from, and what even is a muscle car? How did drivers go from tiny flathead V8s to fire snorting 454s in only a few short decades? And who holds the title for the first true muscle car? We’re hitting the gym, doing some auto-body-building, and getting swole for an all muscle edition of the podcast.
