Hello Tom, I do not own a Cord though the nominal clearance for babbitt big end bearings around the size of your cord crankshaft is around 0.0015" to 0.003" As Mike highlighted there is a difference between the clearance for the Main bearings which is is around 0.002 " to .00325" these age general engineering clearances, I am sure one of our Cord members will give you the recommended factory cord clearances.

Tom.
May I suggest that you get a copy of the Cord 810 812 Service Manual from the Museum in Auburn. It has a huge amount of useful information on our beloved Cords.
From the book the Factory recommended clearances are as follows:
Main bearings 0.0015" to 0.00375"
Thrust bearing side clearance 0.004" to 0.009"
Connecting rod bearings 0.001" to 0.0015"
