BTW it appears from Bill's data that evap cores are unsuited
 to centrifugal water pumps. Makes sense as evap cores are used
 in air conditioning systems with positive displacement high pressure
 piston pumps.

Actually they are designed for a phase change fluid, freon coming in as a
liquid, and boiling in the tubes, with vapor exiting.  Not designed for water
at all, which is why I want to test it.  The GM evap cores have bigger flow
passages than the Ford ones, which would have higher losses.
