340 motor pumping excess oil on right side

Let's go back to the basics here. It sounds like you made multiiple changes on the motor & the oiling problem arose. I would take it back to where you started by putting all of the original parts back on it. From there, make one change at a time & see when the oiling problem begins. I had it drilled into my head from my first hot rod, "Make one change at a time & see what happens."
I wish it was that easy , I sold all my other parts to a buddy who has now moved far away so my plan is to keep it driveable and maybe look for a LD340 intake and a smaller carb like 650-670 ?I believe it has to be the intake swap , thnx
