Stock data for 144/170/200 is:

water neck 1 1/4"
water pump neck 1 1/2"
radiator inlet/outlet necks 1 1/4"

Now, Ford started changing stuff around the later 60's thru 80's for the 200.
Water pumps had longer snouts, etc.
Does anyone have any of the above that show different sizes?
If so, please state year of engine, application.

I am trying to figure out why some of the aftermarket radiator boys are using 1 1/2" and 1 3/4" inlets/outlet sizes(other that stupidity)
