After A/C Add On Engine Overheats Really Bad

Yes it has a fan shroud. I have run a 160 degree thermostat and a flex fan for more than 30 years and the temp gauge never made it to the first mark. As far as I'm concerned it's bone stock, I'm not splitting hairs with fans and thermostats. And I don't think I'm "smarter than Mopar engineers" either. I'm just asking for some ideas and I appreciate the one's I got. Thank you.

When I added aftermarket air to my friends 65 Plymouth it was the same thing. It ran really cool before the ac addition but sucked big time after. it ended up being a problem of the fan not pulling enough air through the radiator due to the condenser. we made a few adjustments to the shroud and installed a 7 blade stock clutch fan and life was good again. it did run a little warmer that he was used to but we put on a mechanical temp sender and it never climbed over 205 even in 95 degree weather(outside , inside was goooooood!)
