Go back to napa and buy a package of plastigage strips if you are measuring bearing clearances. If you are measuring end play the feeler gauge is the correct measuring device or a dial indicator. Be sure the bearing caps are in the right places. They are numbered. Also be sure the bearings go back in the same spots if the were removed.

If the crank is in good shape I would buy a new bearing. Just the set of two that has the thrust bearing built in. An 1/8' out of spec will wear on your timing set.

I can't believe I missed this. It just hit me when I reread your specs. What are you reading that gives you 1.178 inches. That surely cannot be the crankshaft endplay. Allowable end play is only 0.002-0.0095 inches depending on what engine you are working on.
