If you have the stock dipstick use that as a guide, your measuring from the top down not bottom up. The motor doesn't care how deep or wide the oil pan is. Then use however much oil it takes to get to the dipstick mark.
I don't have a stock dipstick to compare to. The real question is??? Are stroker motors different from stock motors for oil levels?? Since their geometry is different, it should be. Like I mentioned, I may be overthinking this.
