A standard Large case 3G alternator will put out around 140 amps stock. There is nothing surprising or special about that, you could get the same thing from a junkyard. Ford 3G and 4G large case units are very strong in their stock form.
...our version of that same unit does 160 amps .... at idle, LOL.
