New to site, new to Mopar overheating issues

It’s not complicated. The OP is down on flow somewhere. Speeding up the coolant is never bad.

That's not always true. I've seen many cars that had too much flow causing an overheat problem. Running straight antifreeze can cause overheating too. The proper mix of coolant needs to take a certain amount of time in the radiator to transfer heat to the tubes and fins. If the coolant moves too quickly through the radiator, that doesn't happen and the coolant is back inside the engine before it cools properly. (removing the thermostat altogether can cause that) You can also get cavitation in the pump if it churns the coolant too fast. That's why the A/C cars used a smaller pulley with only a 6 vane pump. The 8 vane on that smaller diameter pulley made too much flow in some cases. I know, there will be many on here that will say they've done it without problems, and that may be true in their particular application, but, it's not always true in others. There were lots of pulley combinations and different capacity coolant systems with different flow characteristics to make a blanket statement that applies to them all.
