<VV> How about the cooling fans from these engines?

[Ron]

Years of satisfactory use has proven that the 90 degree turn on Corvairs is no problem at all.  I run several Corvairs daily and haven't changed a belt for years although I maybe should just due to their age.

  Again, an assumption with no basis. The main reason I posted these is they are, without a doubt, a LOT more efficient than the Corvair blower simply because these engines are meant to deliver their rated output continuously. And that number is WAY higher than the continuous rating of a Corvair engine! And why stick with the vertical fan axis? This one can be driven without the twisted belt.

Even if these fans were available for $5 apiece, the main problem would be 
their weight, or rotating mass. GM went to great lengths to develop a 
lighter fan, the magnesium version, that wouldn't cause the Corvair's unique 
twisted-belt system to double up on itself, as badly as with the earlier 
all-steel versions, during quick downshifts.
