Oil pressure is coming from the port next to the distributor.
let me be more clear for the lifting off throttle topic - I was saying this only to reiterate that I was not staying full throttle with dropping oil pressure. The pressure only comes back up once you are out of the corner or slow down. Everything in the motor is about 3,000 miles old, change oil religiously and no signs of any bearing material ever in it or the filter.
Running 2 breathers on the valve covers and a valley pan PCV with a ME Wagner adjustable PCV - this is routed back into the intake. I was considering maybe its an excess crank case pressure issue with the stroker bottom end potentially but nothing else would suggest this (no oil being blown out or smoke). I dont think it could make enough pressure to push the oil away from the pickup or stop it from returning to the pan.

Still can add more oil to bring it up to the stock 5 quart level - so at that depth, and the extended oil pick up, I would think the pick up would be covered in left/right turns on a road course with what baffles are shown, and a crank scraper that'll extend from the pan edge to keep oil from riding up the side.
Another photo is of a Mopar pan with added baffle that is a little more coverage to keep oil in the pan.
I am not convinced it is a pan issue since it is a road race pan and should have baffles where needed. The OP also stated he added an extra quart to the already 6 quart pan - so it was overfilled and in most cases can cure the issue.
I have seen YouTube videos for the Accusump used for such type driving, but what they don't show/tell is if the oil pan found on the car being used as a demo has the stock pan or a road racing type pan - my guess is a stock pan which would better demonstrate the need for the Accusump.
What has not been asked is where he picks up his oil pressure. I would tap my line at the oil feed next to the distributor if that has not already been done. I think this might provide a more accurate reading.
Seeing the OP has 60PSI that drops to 30PSI in a right turn, and when he lets up off the gas, it returns to 60PSI, maybe excessive clearance/worn thrust bearing surface as the crank moves forward/backward?
How about installing an AIR BALANCE TUBE between the pan area and a valve cover to help balance air pressure in the pan and allow the oil to easily flow back into the pan? Just a thought.
On the same line of thought, how is the breather/PCV valve set-up?
