Oh BS.
My carburated Dodge 318 Monaco would spin tires easily and my ‘69 Dart 225 did 90mph .Mom Olds 350 would push you back in the seat.
Airbags and ABS are the main things I consider valuable improvements.Especially since I probably would not have survived without them.
Even a 90HP 1.9L Ford Escort would go 100MPH.
