The SAE numbers seem like a much more practical measure. There was so much going on gaming the system to cheat the insurance companies..or maybe the other way around faking the funk to lure customers with overrated claims.

the 1970 hemi was rated at 425 hp at 5000 rpm (officially), but I heard it made 470hp if you revved it out to 6000 rpm...and probably more than 500 if you put headers on it.
