New to site, new to Mopar overheating issues

As mentioned, you don’t need the electric fan. It’s just in the way.

If you were shifting at 8500 RPM that water pump pulley MIGHT be ok. For what you are doing it’s way too big. The pump and fan are turning too slow.

That’s the first 2 fixes I’d start with. They are cheap and easy. After that, if you still have issues you can go from there.

Also a new thermostat is a good idea. Just buy a good high flow thermostat.

That mechanical fan is close enough to the radiator it doesn’t need a shroud. The only benefit to one would be safety.
I wondered that,
That dog wont hunt
Ditch the electric fan all together and get rid of the mechanical flex fan.
Find 18 inch 7 blade ridge fan and a good fan shroud.
Swap out what ever thermostat for a high flow type stat, I use 160* in my 340
Make sure that your water pump is not being under driven, the crank pulley and the water pump pulley need to be at least the same size diameter. It would be best to even over drive the water pump for more flow thru the system.
This should help a bunch your next step is a 2 row aluminum radiator.
PS welcome to the forum, there's always room for one more.

Thank you for the advice! I'm searching for a pulley and fan, going to go ahead and do the thermostat as well and see how she runs then. Love your engine bay, very clean. I see the electronic ignition box, do you recommend that conversion? I think the alternator resistor is bad, because of the electric fan hook up, so I was thinking of converting to the electronic system, something like this Summit Racing® Billet Electronic Mopar Distributors SUM-851003-1
