Don't want to rain on your parade but, looks as if your drain back is at the #1 rod and low to the bottom of the pan. Should be at a main cap and 45* angle to the pan side up at the bolt flange of the pan. So oil spraying out of the rod and oil flow back to the sump will not block the return line flow.
Keep up the good work you doing a great job, I may be wrong but I would not take a chance, since the engine is out of the car.
