Hi Joe,

I've only called him once - had a question about the web page.  I left a msg
on his ans machine and he returned my call later - that says a LOT about the
guy!  My question then was about the next to last column on the
website "Serpentine".  He said if that colume was blank, then the core was NOT
serpenine.  The reason I wanted to talk to him was to find out the internal
flow path in the GM cores.  He assured me they were just like auto radiators -
all the "stuff" goes in one end cap and flows across through all parallel
passages to the other end cap and exits.

I have not yet called him for help to identify a particular sized core - I
don't yet have my cowl and engine and mount - not do I have any cad drawing of
those things - so don't really know how much room I'm going to have under the
engine & mount.  It will be at least 2-3 months before I get my finish kit
with cowl and can begin to play with real world placement options and "space
available".  At that time, if the 2 big cores I have won't fit, then I'll call
him for alternative sizes.
   - Actually, I'm not really sure if I should have the parallel passages
running horizontally (with end caps on each side) - that is/was my initial
thought, to be like an auto radiator.  That makes my 2 cores taller than wide.
   -  On the other hand, if I rotate the cores 90 degrees so the end caps are
on bottom and top, then I'd have the coolant come in the bottom, flow up
through all passages to top end cap and exit it there to go back into either
bottom or top of 2nd A/C core.  In either case, a water valve (like a radiator
drain valve - don't know correct name or terminology - at the top of the first
core would be the place to manually vent air - or simply run a SMALL dia tube
from a fitting there up into the bottom of the pressurized expansion tank to
vent air 'automatically' - that is what I want to do.
     So, if I put the end caps on top & bottom, then I'll probably not have a
need to select a different size a/c core.

Joe, would you "fwd" this pvt e-mail to the Fly Rotary List - or reply to me
with a Cc to the list?  I think this discussion should be shared for peer
review/commentary.
