Alternator amp rating.

What is the max amp alternator to safely run on my '65 Dart HP GT w/charger 273. Still has factory amp gauge and 5 amp regulated fuel/temp gauges. Stock wiring. Factory ac has been removed and no other added accessories. Found a 75 amp rated chrome unit I was thinking about using. any help appreciated.

What regulator is on it, the original mechanical one? Or an upgraded (solid state) one? I would think the only limit would be, if you actually draw 75amps, the field coils have to be fed more current to increase the magnetic field in the alternator... and at some point I suppose the regulator either cannot keep up or could be damaged (or the wiring to/from the regulator) due to excessive current to the field coils. Just thinking outloud...
