Yeah from the list the absolutely nuts, one-off, dragracing versions of cars from the 50s/60s made ~400hp. Which could be outdone by an option on the Camero last year. And if you wanted more it’s not difficult, just more money.
And raw HP numbers don’t take into account how much better modern cars drive or how much safer they are. I daily a car from the 80s and love it. But lack of ABS or traction control or airbags or a collapsible steering column does come to mind every once in awhile. Cars from the 50s/60s will have notably worse handling/cornering/etc.
