My Griffin radiator has conventional inlet and outlet hose receivers.
I was going to cut these off and replace with AN.  I have changed my
mind about the cutting off part.  The inlets and outlets have a very
large base to resist the weight of the hoses and are beautifully
welded in.   Therefore,  I am going to make a plug that has been
drilled and tapped for the AN fittings (in my case --16. ) to weld
into the hose receivers.  Likewise I am just going to weld a cap
(plate) on top of the filler to close it off.   The overflow (1/4"
pipe) will receive a plug that can be opened when filling the system
to make sure no air is trapped in the rad.   It couldn't get much
easier.   Jerry

I think you are asking for trouble there again. I would use 1 3/8 ID
pipe minimum. -16 is one inch ID so 1 3/8 ID is almost twice the
area. As Power Sport says, water flow is very important and you will
have very long lines compared to the rest of us. Greg Richter
is using -24 which is 1.5 inch ID. Your water pump is going to catch 
hell.
