BBC "undercut" oil pump drive shaft

as Paul Harvey said, "now, the rest of the story"

In hindsight, I did not have a problem. The block is a Brodix SBC with raised deck and raised cam. Because of the raised cam, Brodix has it worked out to install a .350" thick spacer between the rear main cap and oil pump then drive it with a BBC driveshaft.

My perceived problem was because when mocking up and checking on the bench I used a rear main cap from a factory SBC block. At first, I did not realize Brodix had made allowances and everything was already as needed.

The oil pan was just hang on the Brodix block for protection and it came to me in a vision to actually check the block and cap that goes with the buildup

!

Once I slipped the pan off I immediately realized the Brodix rear main cap driveshaft hole was about .250" larger than a factory cap.
