150 amps, per page 1910 of my copy of the 2010/2011 XFR Workshop Manual:
"Generator and Regulator - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Generator -
Overview
Description and Operation
OVERVIEW
On 5.0L V8 vehicles (naturally aspirated and supercharger), the charging system consists of a 150 Amp output generator and regulator assembly. The generator and regulator assembly generates electrical power for the vehicle electrical system and maintains the battery in a charged state.
When the engine is running the generator produces an alternating current, which is converted to a direct current internally. The output from the generator is controlled by the voltage regulator (located inside the generator) and then supplied to the battery
through the main battery positive cable. The generator is mounted on the front right side of the engine and driven at approximately 3 times engine speed by the accessory drive belt."
Didn't find anything under "alternator", coz the sneaky buggers have called it a "generator"!

If you want to go to a high amperage (250 or 320 amp) I have a shop I've been dealing with for about 12 years up in Yucaipa. The can rebuild your stock alt to this spec. I have their 250 amp (145amp @ idle) large case GM alt on my truck, and had their 200amp units on the G35 and Z28.
250 is more than enough power for your needs. You'll need to run an additional + cable off the back of the alt (gives the same effect of running heavier gauge wire) to the main power block in the engine compartment or to the batt.

Hey @Bigg Will, any chance do you know if the shop still is in business and does this type of work? If so do you think I could get that shop’s information?

Make sure they replace the voltage regulator if it's a rebuild or upgrade of your alt.
