    Ernest,
      I am still planning on remote radiators but not as far to the rear of the Delta as you have indicated. I plan on mounting a GM evaporator on each
side of the a/c to the rear of the firewall between the second and third rib
inboard of the Delta centersection. the large 9.5"x13" evaporators fit very
well here. I am using a NACA report on radiators buried in wings from the 1940's to size, shape and position the inlets and outlets. I will use alum.
tubing and short hose connectors. Not sure of what size yet but will be larger than 5/8" but smaller than 2". I am leaning toward 1.25" or 1.5".      I am considering running the alum tube inside a duct that I can put
cooling air through.

Kelly, I worked up a spreadsheet to calculate the weight of coolant and head pressure for different tube selections.  You specify the flow rate you want at the far right and it computes everything else for you.

You and I may be the only two builders in the world contemplating remotely located radiators.  Is that an indication of something?
