New to site, new to Mopar overheating issues

My understanding of heavy duty cooling vs standard cooling is that heavy duty cooling added a shroud, a more bladed fan, and a larger capacity radiator, which could be a physically larger (wider) core, and/or an extra row (or two) of tubes. The pumps stayed the same if the pulleys stayed the same. You can add a fan clutch to a non-A/C car if you want. To me it reduces air flow at low speeds and just adds one more thing to fail eventually. I prefer to use a rigid fan for max air flow at low speeds. I'll accept the slight HP loss. At higher speeds, a fan of any type isn't even needed. Ram air does the cooling. If you have A/C, eliminating the fan clutch can cause a belt squeal problem in many models. (been there, done that). It's all about the ratio, fan drag, and belt tension. I also prefer 180 degree thermostats for many reasons. 194's increase the underhood temps too high for my liking. I would rather not BBQ all my wiring and hoses. Doesn't hurt the engine however. 160 is just too cold to get the heater to work correctly and sometimes the engine just doesn't get up to it's proper running temp. That used to cause engine sludge (not so important today with our better oils), but, it can still allow moisture and other contaminants to build up in the oil. 180 just seems to be a happy medium. You can argue all you want about "no such thing as too much flow", but, as Loggato just mentioned, and what I've discovered over the years, you can have too much flow. If you just look at what they do in race cars. No thermostat is used, BUT, you have to put in a restrictor washer in it's place to REDUCE flow. Coolant needs time in the radiator to transfer heat. It's that simple.
