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

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?

I’m having hell trying to find proper fittings and taps to build the crossover.
Just Spent 30m in the back parts aisle of Autozone sifting through brake line tubing/fittings and never came up with something I could use.

Been to Home depot, Lowes, and O’reilly, and Tractor Supply too.

Bought 1/8” and 1/4 pipe taps.
3/16, 1/4, 5/16, and 1/2” long drills but nobody stocks a 9/16.

What a pita.
Next up is plumbing supply house.
May have to break down and just get everything online through eBay or ship to store. Uugh.
