Stroked motor oil levels?

You are kinda doing it backwards Kent. If it’s a 7 quart pan put 7 quarts in it and mark the dipstick. Never trust a dipstick you don’t mark yourself.
I can't be sure what it is. It just looks like one. It is an no name aftermarket that came on the motor. Surely there is some formula for setting the oil level relative to the crank or block or windage tray. You would want the most possible knowing that while running the level would drop because of the oil being pumped into the motor.
Without knowing what I have and having an aftermarket dipstick as well, I have no reference point to check the dipstick. Some pans are measured with and some without considering the volume in the filter, further confusing the matter.
Another site but this is an aftermarket dipstick as well, not stock.

Doing the math to find depth, These measurements would tell me that full is 2.250 inches below the stop and low is 3.875 below. This is the measurement that I seek to verify my components are correct.
