Thanks in advance for any thermostat advice. I was just about to
install
the thing, but maybe I'll hold off a couple days.
Cheers,

Rusty, you can plug the hole with the water pump housing on the engine.
You
will need a 1/2" NPT tap (if memory serves me right) and I find a socket
that will hold the squared end of the tap. Then using an socket
extension I
can put the tap into the hold and cut the threads for a plug. Suggest
suffing some cotton with vasaline coating or other means of trapping the
metal chips below the hole you are tapping. Then flushing it good with
a
hose.
I tried a thermostat twice and could not get it to cool properly on the
ground in either case, so gave up and have flow 200 hours with no
thermostat
and no problem.
For those of you not also participating on the "other" list; attached is
the flow data measured during my 20B dyno run with (full open) and
without the thermostat. Considerably higher flow without. Higher flow
= better cooling. However; some means of controlling temp and speeding
the warmup is generally necessary. Either control air flow, or, if you
have two radiators like I do, consider an in-line thermostat for one of
the rads.
