One word my friend...NAPA.
I have a 350 as well, though it's TBI. Mine requires a 192 deg t-stat. Using my OBD I scanner I can tell 'exactly' when it opens up. When I first put the motor in the PO for some reason put in a 180 t-stat....killed the gas mileage.
I personally wouldn't worry about the temp climbing up to 210....no real need to turn the fan on until it goes over 212. If you have a tight system (holds pressure), you should be able to go to 240+ before you worry about the water boiling.
Now it is possible that your new 195 is not flowing as well as it could.
Just go to NAPA....I would much rather pay a couple of bucks more and do it once than save a couple but end up doing it over anyway....
