Shim the oil pressure relief spring and see what happens.

I would think that because the problem changes with angle of the pan up or down hill somehow the oil level goes down enough to effect pickup, if it was my engine the concern would be what RPM does the pressure dip happen and does the oil pressure drop low enough to cause bearing wear? That engine has a windage tray I would think crank whipped aeration would be low on the list as a cause. It would be interesting to see a video of what's happening I wonder if anyone has come up with of a drain plug fitted end scope camera that would be cool.

I believe if you move the pickup to the aft center corner of the pan all will be good.

Nobody has asked I don't believe . Did you check or verify the location of the oil pickup to the bottom of the pan ?

And you need 1/2 clearance pickup to pan with a Canton pan.

Yes, used clay to measure and make sure it's not sitting against the bottom of the pan. -Steve-

Regardless of all the hypothesis here, 40PSI is totally sufficient. Drive and don't worry about it

If he has 56 PSI and it drops to 40 PSI when he floors it, please explain how the pressure relief spring is an issue? (it's not) It was just 56 PSI two seconds prior.
