That was you Jerry & you have a point. Its the major reason why you see higher oil pressure readings in a cleveland block ( which has the oil pressure fitting at the rear end of the main gallery ) versus the lower readings on a windsor block ( which has the pressure fitting at the front just in from the filter pad in an area where the main flow goes past the fitting as opposed to flowing directly at it), both motors run the same size oil pump gears, & yes there are differences in bearing sizes etc.

A bit hard to prove in a windsor unless its an aftermart block with priority oiling that will allow shifting the oil gauge to the rear, but easy to check out in a clevo by swapping from front to rear.
