Cool story. When I first saw it I thought the RTS was the Sonic Cuda, but its not. In the late 1970's I bought this '72 Cuda from a friend who was the original owner and had the Sonic-styled paint applied. Was a 340 4-speed car.
Barracuda in the background was a '64-1/2 that was originally a 273 4-speed car that later got a 340 6-pack engine bought at a boneyard from a wrecked T/A Challenger. Like the guy in the video says, back in the day these were just cars, and we drove, modified, and raced them without giving it a second thought.
