    What is a two pass rad?

    OK that is when the water goes down one side and comes
    back the other. Sometimes called a Sciroco type.
    Makes plumbing a lot easier.

The stock radiator Tracy is currently flying is a 2-pass.  I had to have
a couple of mods applied to it for my use - I milled off the radiator
cap and welded it shut.  Also, for whatever reason the rad came with one
port 1.5" and the other 2.0".  I had the large one milled off and a 1.5
put in it's place.  But it's a nice rad, just tricky to mount.  If you
come by, Doc that would be an area you could give me some suggestions,
since this is the last remaining design area I have no workable plan for.

I see what happened Mark. The neck is on the extreme left instead
of in the middle. It helps if it is the middle. Not fatal however.
