Is it .008-.023?
.0008 seems really tight and plastic gauge doesn't go that small.

A sheet of paper is ~0.003" thick to have something from the real world you can relate to
Pete McHenry suggests ".0020"-.0025", with half a thousandth looser on the rear main"

Plastic gauge day!
Wet sanded the #1 journal with this new-ish 3M paper that is equal to 1200 grit and 5w-30 to get rid of the slight scratch that I could feel with my finger.
A little Vaseline to hold it in place.
Got this bad boy dialed in to 25ft/lbs and 55 degrees.
Looks to be .001!! Thank god
For reference

Snap, I am glad I'm taking my time. I've noticed a couple of key issues especially the teeth of the crank sprocket being rounded off. If I was rushing I would probably have missed this and might have had it apart again in another 300 miles.

Where did you get the plasti gauge stuff from? I will need to do this when I start reassembling my spare block.

I know NAPA has them. Any parts house should have them.

I'm just terrified that I'm going to blow this up so I need to do it the right way.

I think I did it right. Tried to keep everything as clean as possible. Rubber gloves and brake clean were flying everywhere!

What is all the white stuff that you have on the main bearings and caps? Assembly lube of sorts?
Are you replacing the crank sprocket? You had mentioned that it was rounded.
Looking good!
