I drilled and tapped the oil ports for 1/2NPT (from 3/8NPT) in preparation for a remote filter and/or external oil pump. I moved the port that comes from the oil pump over a small amount....in case I ever want to use a block mounted filter, there is still room for the adapter to seal. It's close.
To plug the 'old' oil filter port, it's the same thread as an -8AN ORB plug...and there is already a nice looking chamfer for the o-ring to seal against....so I'm gonna try using that method.
