So what IS a muscle car?

I was talking to a guy this weekend about his corvette. He said when he bought in the 70s he was hauling *** down the highway in the middle of the night and his buddy said there’s a car catching up to us. He said it’s either a COP or a Mopar. Sure enough he said it was a Mopar, a Coronet Wagon loaded down. Passed him up like he was sitting still. The old man driving just waved as he passed him at over 100mph
In 1975 I was in a Mopar club. We were in a member’s 1969 Super Bee that had a lot of Direct Connection parts including a six-pack on the tricked out 383. We were doing 70-75 on the 10 Freeway when the car was rocked side to side by a 1964 Jaguar XKE. The dude was pulling hard past us. We chided the driver of the Bee and he cut in the six-pack. The shotgun passenger spoke up after a few seconds and said that he was doing 120! The driver said that he wasn’t full throttle yet but that we were starting to gain on the Jag. Just then the Bee was rocked side to side again and we all looked to the left to see a California Highway Patrol car. It was a 1969 Polara with the 440 Interceptor engine. The officer glanced over and grinned at us as he flashed by. The driver of the Bee eased off the throttle and brought the car down to 65 MPH because there might have been other CHP cars coming up from behind.
