take out the stat from the car and start driving. that will eliminate the possibility of it not opening. if the car overheats with the stat out, you have a different problem.

Probably not what you want to hear , but I had a mustang several years ago that was doing the same thing. It would sit and idle and never overheat and if you drove it somewhat respectable it was ok. As soon as you beat on it a little it would push all the coolant out the radiator and overheat almost instantly. Chased my tail for weeks and finally pulled the heads and sure enough it was a bad head gasket. Just pushing compression into the water jacket.
Oil was always clean and so was the coolant.

Maybe have everything pressure tested and double and triple check everything first. Hopefully it turns out to be something else.

Good luck man

Use a block test kit... ~$40 from NAPA.

With this kit, you take a sample of the air space in the radiator with engine running (instructions tell you to remove a few inches of coolant from radiator), if the blue dye turns yellow then there are combustion gases present in radiator.
