I think you are trying to use modern methods on this old girl and are missing the point of the shims. There is no "crush" on these engines. The bearings are babbit and "fitted" to the crank with shims. New bearings are scraped to just fit the journal. Then you lube them and install the rod on the crank. I usually hang them down from the crank as you don't want the piston in the bore while fitting the rod. The idea is to add or remove pairs of shims until the bolts are tight but the rod is just free to rotate on the crank with very little side play. Some use plastigage but I just set them by feel. It takes awhile to get this right, but you will find the point where the rod just begins to resist being rotated, then add back in one set of shims and your good to go. Install the piston in the sleeve and tighten the rod bolts, install new cotters in the nuts.
