You do understand that oil does as much cooling as it does lubricating. Unless you have a separate oil cooler, the only cooling it would get is from the cooling system. It therefore would be higher temp than the coolant. 250 oil versus 210 coolant does not seem out of line to me.

only by sending out a sample to a test lab will tell you how long it is good for.
when you change the oil you send them a sample, they will tell you all the contaminants in the oil as well as the overall condition of the oil itself. most people that i know that have ever sent in a sample found out that they changed their oil too early and could have driven on it another 3 or more thousand miles before the oil lost its ability to protect.

Your cooling system is marginal to get that hot just driving down the road at 70

Ideally, you'd like your oil quickly warm to just over 212 degrees and stay there. 212 will vaporize the liquid water, a byproduct of blowby, and this vapor can be cycled out of the engine via the PCV system.
Also, hot oil lubricates better than cold oil.
Not sure why some of you are running 40w and 50w vis. That's a needless drag on the engine. How about a good quality 10w-30?

My 78 L-82 use to run about 225 degrees water temp and 250 on the highway (I have an 80 oil temp gauge in place of the clock which I installed 25 years ago) with the OEM cooling system (radiator, shroud, fan clutch, water pump). I installed a Dewitts aluminum radiator, Stewart aluminum stage 2 water pump, High performance Robershaw 180 thermostat, new correct hoses, etc about 2 months ago, and the car now runs about 170 around town and 180-185 on the highway with the oil temp running about 200 on the highway as well. As an aside, conventional oils start to breakdown around 250 degrees while synthetics have a much higher resistance to breakdown at about 325 degrees. Another reason to run a synthetic oil to help with the cooling!
