Running without a thermostat ok?

It usually runs about 193, but by taking it up hill air on and floorboarded I could only manage 219.

So apparently, 219* is not a cause for concern? If my old truck got up to 220*, I'd be sitting on the side of road in the shade and waiting for it to cool down. Btw, yes, spec'd, purchased, pre-tested, and installed new thermostat.
