I did put the 195* in and didn't see a difference but this again was as the distributor was failing so not a good idea what it did or didn't do for it. One thing I found interesting was adding the water wetter, I have run it in one of my other cars and it did drop the coolant temp around 10*. I agree 195* isn't hot, heard years ago that Nascar runs theirs at something like 220*, many modern cars trigger the fans at 212*.
