Looking thru all our stuff over at the netreg site, it seemed the car came with the 180* as OE.
Also, in the distant past Stant had a miss-box happen and people got a ford stat(?) in the LT5's stat box. The results were not very satisfying at all.
When you say "driving around" do you mean highway or secondary streets? I ask because the observed behavior of the gauge seems just like my gauge behaves if I'm doing the around town, 40 mph or less thing...no B to B traffic, but no above 50 stuff. If you are describing 50mph or better as in highway use, then yea something is wrong for sure as the gauge should be reading about 1/2, ya know around either side, but not toward the 3/4 mark. Only other reason I can think of is that the gauge's sensor picked that moment to go south on you, or it's air bound.

No thermostat swap yet -- but I have one on order, (the stant 180) so I'll be changing that, as well as what is presumably the original 20 year old radiator ( I think the coolant I drained out was the original coolant
).
The temp would creep up under load -- at steady cruise it would hang around 2/3 up, under heavier load more like 3/4. Idle was 1/2 way.
