Quick update. Sunny New Years Day. 35F outside so took opportunity to roll the tires and basically heat the car up a bit. I was curious how the thermostat would work with now 2 bypass holes rather than 4. This is a stock thermo.
At cruising speeds 55-70mph, coolant temps stayed at ~ 185F/85C. Unlike before, driving around in 35F weather would have caused the coolant temps to drop down to 150 or so.
So overall, the combination of a Fluidyne rad w stock thermo (w 2 bypass holes) seems to have given the result I was looking for.
