For Myself If I had decided to drive the Car in the condition described I would have done so expecting the Engine to be damaged.
It does sound like the haromaster87 got away with it.

I had an issue on a Gasser where I had tried to re-solder a seam on a Radiator.

I was in the 2nd lane on a 4 lane Freeway in somewhat heavy traffic when I suddenly overheated (the seam on the Radiator had opened).
I was not going to stop the Car dead in the Middle of the Freeway even though I knew I was not going to be able to get off of the Freeway fast enough to avoid serious damage; I actually managed to get off of the Freeway before the Engine started knocking.

I had plenty of Oil but overheated Oil does not lubricate well.
When I took the Engine apart there were melted Rod and Main Bearings and Cylinder scouring.


Part of the reason for some of the critical comments is that other people read these threads.
The critical comments might give some people some prior though on what to do in these sort of situations.
