Assuming the radiator has plenty of capacity to cool, I would expect the temp to run much closer to the T-stat rating. If you had a 195 T-stat would you expect the temp to run 215 down the road? My 347 runs 185-190 down the road with a 195 T-stat. In town it runs 195. I cannot say my gauge is accurate, as I have never checked it. However over the years, my daily drivers all seem to read close to the T-stat rating.
