Sorry, but that's a bunch of baloney.
The definition of a horsepower has not changed. It's been 550 ft-lbs per second since God was a boy.
The reason a Farmall M had more horsepower when you were in high school was due to the overbore "firecrater" style pistons that were put in them when the engines were rebuilt. Cubes were increased. Compression ratio was increased. Hence, more power. 50 was normal for a rebuilt engine then, and 57 is normal now because of even bigger overbore kits, better parts fit, better materials, and planing the head and block umpteen times over the last 70 years.
The horsepowers used to measure 39 then were/are the same horsepowers used to measure 57 now.
