Cut my teeth working on M37, radio and ambulances.....

I am not sure that you can easily convert a 251 to full flow...... having said that with sufficient $$$ and skills anything is possible.. I wonder why you would want to or feel the need to do that..... Oiling and filtration on the Dodge 251 has never been a big problem.. Overrevving and throwing connecting rods is another issue..... and they do run well on 5 cylinders with a gaping hole in the engine block stuffed with rags.

On the oil pressure relief valve..... it is triggered by oil pressure and not by temperature..... in fact 135 degrees for oil temperature would be far too low for a regular gas engine and would result in serious sludge buildup. I would expect the oil temp. to be above the coolant temperature....probably in the mid 250 degrees F at normal operating speed.

I am also in the region.....across the river from Gilles.....across the big river!!
