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

Read these 2 pages.
You are given 2 options to upgrade oiling system.
One is restrict flow and open passages so it goes where you want it by tubing galleries.......

The other is to close off #1 main gallery feed to passenger side and install crossover tube to feed #1 bearing and drivers side oil gallery.

It States both are feasable options for up to 10k rpm engines.

Yes, the pickup tube and pan should be modified to support the increased oil requirements of high rpm demands.

This mod was CO-INVENTED by Larry Schreib and Larry Atherton so it says on the first paragraph of next page.
All blocks were sent to Bob mullins and Co. for the modifications to be performed.

Method 1
Sleeve the right oil galley and plug the left side front passage at the main journal saddle. This method is for solid lifter or solid roller cams. The lifters are splash lubed.

Method 2
The crossover tube method is used with hydraulic lifters. Everywhere I have read this was created by Larry Atherton although others have joined with him to published books that contain these methods.
It was designed to stop the starvation of the rods created by the right oil galley on the number 2 and number 4 mains
Page 9 of GJs thread talks about this and has pictures.

Any one interested in the oiling mods I did?
