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

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.

When you drill for the crossover you must be careful to place it at the proper angle. Otherwise you will not be able to screw the 45 degree fitting in.

Start with a small bit and work up in size.

You need a 7/16 drill bit and a 1/4 NPT tap
