Most posters here are recommending bigger radiator, larger fans etc. But let's go back. At one time, not long ago, the OP stated, the car used to run cooler. So we have to assume, "something's changed". Starting from that assumption, the most logical path is to try and determine what has changed, not start changing parts. Since the car runs the same with no thermostat, you can eliminate that. You stated the radiator is been gone through, so all that's left (asuming the fan is running properly) would be to look at the amount of heat the engine is generating. Something has changed there. And running vinegar through the motor will not solve the issue. Your coolant is getting hot, so the transfer of heat from the block to the coolant is happening.
The second area to look is the flow of coolant through the system. Is there a blockage?
I would be looking at the vacuum advance some more or perhaps a slightly lean condition in the carburetor. I would also look closely at the hoses on the radiator for restricting flow of coolant.
Some of you guys have more egg on your face than the OP.
It is a 1965 car. "Google check says" .....................? Get serious, modern emissions cars run much hotter than old designs.
The OP found what he did wrong, corrected it, and posted it.
Posting without reading the other posts is not a good idea.
baloney. I had that exact same motor, many years ago. You could buy a 180 or a 195 for it. With the 180, it always ran close to 190, not much different than "modern cars". The laws of physics have not changed much since than.... I had thought the OP stated he tried running it without a thermostat. Guess I mis-read.
