Bob,
Thanks for clearing this up. What I had written earlier was how it was
explained to me years ago (and just goes to show how long someone can be
wrong and not realize it.)....
Then again, I could have misunderstood what he was trying to tell me,
too... still, my fault.
Thanks for setting me straight!

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.
Regards,
Bob Helt
