I'm going to pressure test the system tomorrow, run the traps on the pulley dimensions, and try and sort out whether it should be 100% coolant or 100% water, as both have been recommended in this thread thus far. I will burp it yet again and try jamming more air into the nose. Unless I see a breakthrough, I am removing the shroud and digressing back to where it was running cool while moving. Then I can at least safely drive it to the radiator shop for further eval.

Thanks for all the replies, I'll post again tomorrow.
