If you STILL have not installed a graduated aftermarket temp gauge and are still relying on that factory gauge for your reading, and thinking 195* is hot, then you may as well sell the car now. 195*F is NOT hot. My 331 regularly hits 240*F and no damage results from this. I'm sure it's also gone hotter too. Do I like it doing that? No. But I've learned to live with it.
I will order an aftermarket gauge, but how would I know if the car is over heating or not without a gauge let say if im driving it. are there any symptoms to watch out for.
This is my first classic car im used to new car with actual readings, I dont want to be careless an drive the car when I shouldn't.
So i decided to have another look at my heating issue with the feedback I received.
I got myself a digital thermometer made a simple holder for it - pictured below,
Topped up the coolant
The starting temp of radiator coolant was at 92F with the engine off
I started the engine (cold start) and the coolant temperature rose gradually to 195 which was HOT or the max then I stopped the engine (@ 115F the needle was in the middle)
When I stopped the engine the coolant started to flood and came out of the over flow tube, a lot of coolant came out, pictured bellow and in the video
I just finished installing a fan shroud and a lower hose spring and I changed the thermostat (195) recently and it seems to to make a big diffrence I will put on a new radiator cap also. While the engine is idling the radiator runs at 195 degree F using a thermometer in the radiator, seems good to me.
I would like to know how to install a second Water Temp Gauge, please follow my new thread for your suggestions.

I have one of these, JEGS Liquid-Filled Engine Thermometers - JEGS
If you have a factory style cast iron thermostat housing with the temp sensor hole, this will screw right into it.
my factory gauge is almost over the high end limit and ther mechanical one shown above is only reading 200
