My take on the oiling system crossover tube for the small block

MAc I never had exceptional problems with a cross drilled crank and half grooved bearings
IMHO the oil has nowhere to centrifuga out to (the bottom bearing shell being solid)
but did have issues with cross drilled cranks and full grooved bearings
anyone else dremel a NACA duct leading the crank hole? aka "teardrop" with the drop being the hole?
