Yes, my 5KT did at about 65 MPH going South on I81 in Virginia.  Not many
indications of problems although oil temp was a little high but I had just
climbed one of the longest hills in the East. A rod bearing let loose due to
oil starvation.  Rebuild found some foreign material in the oil temperature
thermostat that caused lower pressure at the rod bearing that failed.  A
previous monkey lad used silicone plastic to try to cure what he thought was
a head gasket leak that was really a head crack;  it's a very long horror

Car was towed on a flat bed to Alexandria where a shop there rebuilt it.  A
very long ride in the cab of a tow truck keeping the driver awake swapping
stories about what he could see from his cab when passing cars, etc.

Still have that car and engine, although I'm looking to replace it.
