Thanks, I will have to look at mineThe 440 in my RR had two tapped oil provisions. 1/8" NPT IIRC. Not mine - a pic I grabbed off of the devilweb.

That's how I did mine (383). I didn't know about the other port at the time.Can you tee off the oil sending unit to run an oil pressure gage and still keep the idiot light working on a 1969 Plymouth roadrunner with a 440.
I am also running this setup on my 440.yes but you could remove the other galley plug and plum it from there.
