<VV> Astro 1 engine fans

[ScottyGrover at aol.com]

I have studied the Astro fan drawings, and here is my best interpretation  
of the shape of their fan blade, applied to the basic Corvair fan.  I have  
no doubt that 3 fans of this type (smaller, and with a different bolt 
pattern)  could be used on an overhead horizontal shaft, each fan serving 2 
cylinders; but  the top cover would have to be redesigned to maximise the cooling 
effect.

Now that  I've been given directions on how to actually search the VV 
archives,
I'm  emboldened to ask this question regarding Corvair engine fans:   Has
anyone attempted to replicate the Astro 1 overhead cam engine  cooling
system?  (I didn't see any obvious references to attempts to  replicate this
system.)

The Astro 1 engine was a major redesign to  incorporate a number of major
improvements to the Corvair engine.  The  major one was the SOHC design, but
the cooling system was also radically  different in that it used three 
blowers
(squirrel cage?) on a single  horizontal shaft.  The fan routing was
simplified to eliminate the 90  degree bends and looks much more like a
conventional layout.

I've  seen some of the Porsche fan adaptions to the Corvair engine so
itseem  pretty obvious that the fan belt
routing could be done on a more or less  stock engine, but has anyone
actually investigated the fans  themselves?
