Oh.. treble that

yep, mine is rated 140A

But only for a short time.

That's not my experience for a Chinese sourced Bosch replica on a boat
application, where the alternator will happily kick out 150A over a
prolonger period.

One of the reasons why high amperage alternators is specced is all the
electrical power needed when all the car appliances are used, rather
than just topping up the battery between starts.
