Brian,

By the way, here's my photo of 3q. in the pan:

And here's the best photo I've got showing that the 3q. corresponds to the
FULL mark. Not quite so obvious is that the rod caps will just clear the
oil pool at that level -- avoiding the foaming and power loss that would
result if they became submerged.

All of which says that your temporary sight gauge should show FULL at
4-3/8" below the pan flange -- IMHO.
