Were  crankshaft bearings ever available as "oversized"? Were crankshafts 
ever made  by GM with jurnals that were too big requiring bearings that would 
not be  standard sized? Or do we all mean to be saying undersized?

Timothy,
Crankshafts are ground to certain specs. When done so, the bearing used are 
 called standard size (even tho they may be different sizes for each 
journal).  When a crank has been reground to lessen the previous diameter, then 
the bearing  used must be undersize....all per Chevrolet and industry 
standards. Corvairs  never used oversized bearings. Look in the P&A parts manual for 
some  examples.
