Got the B series crank main and rod journals measured, and also installed the main bearings and torqued the caps down to measure bearing inside diameter with a bore gauge for oil clearance measurements.
The clearances will be in spec, although a few measured to be at service limit, but I believe this to be differences in bearing washcoat thickness. Next time I do bearings in this engine, I'm going to have a stack of 3-4 sets to pick and choose equal to find bearing shell combinations that are more even.
I shuffled the bearingas around, until I came up with the best combination of which bearing should be installed around which main journal. See 3rd sticky note (right most note to see the oil clearances.
I then labeled the bearing backs with a scribe to denote which bearing shell should go which journal when I get them back from WPC treatment (B is block side, C is main cap)
Then tried out the B series breather/black box delete AN fitting kit I picked up years ago. I had NO idea where these were supposed to go, until I stared at it long enough with a flashlight lol
Should work out pretty good with the existing breather/car can.
I'm also ready and setup for tomorrow to measure rod bearing oil clearances with caps torqued and bolts stretched to spec, weighing and shaving the rods, then getting them installed to the pistons:
Then I can gap the rings, install piston/rods to bore, and then get the head bolted on so I can install cams and begin mockup of exhaust manifold stuff.
More fun stuff tomorrow!!
