New charger is running hot...

Once you get your coolant leak fixed and the shroud installed check your timing.

34 degrees timing...

Seriously, what is the problem with a 160 stat ?  My 440  (26" rad.) used to run barely warm till I had it rebuilt then it ran hot. I flushed the radiator a couple of times  and then it ran tolerable so I put a 160 in it and the temp. is fine.

I was told the 160 doesn't allow the oil to get hot enough to burn off moisture.  And something about the cylinder walls being cooler with a 160, having a negative effect on efficiency.  I heard several explanations so I switched back to the 180.  Just an FYI I tried an infrared thermometer above and below the 180 thermostat and found the factory water temp gauge was off by 20 degrees (high).

Yes, too cold an engine is as bad as too hot.

Also if you drive your car in the winter the heat will suck.
