I've watched this same video a number of times, but for some reason it being on POE makes it so much better. I love old engines. There's another one probably in the related videos that has some interesting noises too, something like "600 Snow engine". 600 horsepower, but 39,000 ft lbs of torque, which I guess was just sort of how those old ass engines were, no horsepower and miles of torque.
