Dave,

I have been driving both my 3 and 4 in 85 + days recently and they never get 
much above 185 unless I am stuck in traffic for more than 5 minutes or up a 
real long hill. Even then just above the 185 mark.

Since your engine is rebuilt I am guessing the water jacket is clear of gunk. 
So it could be your radiator, coolant, water pump or thermostat. I use a 50/50 
mix of antifreeze and distilled water.

Both my 3 and 4 use the stock TR4 4 bladed fan.
