In town traffic caused it to rise a bit further to about 215F. Oil pressure dropped from usual 38-40# running down to about 32# while running, 20# idling.
I've optimized the cooling system by every possible move short of shrouding the front to the radiator which I will soon be doing and in ambient temps under 95F it runs very nicely from 185-195F.
Summers are really hot here; I know some of you Texans and Arizonans have high temp outdoors experience...how high can I run a stable temp. without harming the engine? Should I be measuring oil temp too? Cylinder head temps?
Thanks for any replies!

dirk,
i don't think it will hurt it, i have hit those temps now and then. i have also pulled over sometimes,when i can, and let her cool off. the shrouding may help, but when its that hot out there isn't much you can do to prevent it. if you know your going to be driving in extreme temps, you could turn the timing back a couple degrees, that usually gets me around 10 degrees less temp.
