A lot of the 'underated 500 hp' monsters from the late muscle car era would be rated at something like 400 hp today. SAE gross vs SAE net.
Yep, some of those cars were "underrated" on an "overrated" system so to speak.
Seriously though, I would love to know what some of the classics would be rated under the current SAE standards for certification.
