Thanks for clarifying that.

Do you have one of these?

No, the only micrometers that I found at Harbor Freight all had the blunt tip.
OK.

What's the ID of the large end of the rods 1, 2, & 3 without the bearings installed.

We'll reverse figure this one out . . .

ID of the big end of the connecting rods without bearings installed all measure 1.772". This measurement was the same for all three rods.

Your nominal rod bearing thickness on #1 is 0.0580"

Your nominal rod bearing thickness on #2 and #3 is 0.05825"

If you would install rod bearings with a thickness of 0.0585" in all 3 rods, theoretically, your piston to crankshaft clearance will be 0.0015".

I just happen to have a such set of rod bearings.
