But it continues to warm up until the needle almost touches the square under 220 on the temp gauge. Can the original temp gauge read incorrectly or are they pretty accurate over the years? What is the proper running temp of a 235 in-line?

If you are running close to 220 while the engine is running you probably need either a thermostat or a boiling out of your radiator. If you are concerned about the reading being high after shutting the engine off that is normal. You still have all of the heat in the engine with no circulation to get it to the radiator. The coolant still in the engine will get quite hot & your gauge will reflect that.

Your engine should run with 10 degrees or so of the temperature stamped on the ‘stat. You might try taking it out and placing it in a pan of boiling water, it should open fully and then close completely a few minutes after removing it. | | |
