Pusher fans are almost always worse than pullers, I would definitely not install it that way.

I get it now. Puller it will be. Additional responses are unnecessary unless you want to make fun of me.

This site is great, nobody will make fun of you, but they will add their experience(s) which is invaluable!
 

1994 BMW 525 had a puller electric fan behind the radiator, and a pusher in front of the AC condenser.

Look into the v6 contour dual fan set up with a 24” rad, for all I have read it seems to be the best way to go for best electric fan installations.
After I installed a 331 my progression through fan installations went from electric pusher to electric puller and finally a fixed solid mounted 5 blade mechanical fan .
I have a 24” Champion aluminum rad with a custom shroud, a factory 17” 5 blade fan cut down to 15”
and a 180 degree thermostat .
With this set up my  temperatures have never gone over 185 under any circumstances.

 
Ya butt...you live in the great white north. 😁

My 65 with a built bored .60 over 289 ran very hot especially in warm 80+.I still run the 180 stat.  I made a call to the guys at champion and they said my 2 core 1" tubes stock size champion rad  rad with AC would never cool. I went with there 24" 67-70 1" tube 2 core and there 11" Spal fans and now I dont see 195 with the AC at 65 MPH or even at idle. Best move I ever made. And with some minor mode the Optima Battery is still in stock place

I would first advise you run at least a 180 degree t-stat.  160 is simply too cold.  If you are trying to stay ahead of it getting hot you are better off trying to find another solution.  Running an engine that cold messes with the fuel/air mixture, and requires carb settings that are not ideal, especially once it warms up.  You are also risking much faster wear, even at only 20 degrees less than the factory t-stat.  We worry so much about overheating that there's an unfounded tendency to believe its impossible to run and engine too cool.  

Run one of the good puller fans and your issues will go away.  I run an old copper/brass 3 row with a SPAL single fan and it ran 205 in 100+ degree heat.  With a system pressure of say 13psi you don't need to worry about overheating until it hits 230.  Boil over is about 250 with a 50/50 water/antifreeze mix.
