A lower temperature thermostat won't do anything to the coolant temperature because it too will be wide open just like your 195 stat. You don't mention what temperature your coolant runs now so we can't tell if your temps are correct or not. Turning the fan on earlier also won't do anything if you are under way.

First try cleaning out the fins on your radiator, C4's suck up all kinds of debris and the bottom of the radiator gets clogged. Some pictures were posted of clogged radiators awhile back.

Turning a fan on at 160 with a 195 stat is not going to do a thing. with a 195 stat your temps are right on.

Good advice! also, replacing the radiator with a hi flow 2 or 3 row will really help a lot. One thing that really worked for me besides the 3 row radiator (I have a 383 too) was to install an oil cooler, since I run it at the drags frequently. I now run at 188 to 204 in Miami's 90 plus degree heat with a 180 degree thermostat. I use a 50-50 mix of water/antifreeze and a bottle "water-wetter" in my radiator.

Missing or damaged air baffles (up front) or the shroud that directs the air flow to your radiator will also cause overheating if they are damaged or missing.

My next install will be to add a transmission cooler which should also aid in keeping the temperatures at a reasonable level, and protect my trans as well.
