1/2 of one outside main and 1/2 of one center main bearing has a .001 sized
bearing in it.  All of the other pieces are std.  Why would the general do
this?  All of the bearings look good, not worn much at all.  I think that
I'll have to send the crank in for inspection of size, but these .001 halves
have me baffled. Input please!

The answer came on Buffalo this year from the panel discussion at the
Convention.  General Motors could not always maintain the tolerance
necessary for the standard size bearing. Quality Control would mark the case
and the Assembly team would put in a matched bearing shell. Unfortunately
that was so long ago that the members on the panel did not remember what the
markings on the case for the oversize were. This is an opportunity for you
to carefully inspect the case for any markings which might be different on
the center main. Please report back on anything you find, paint? Punch
marks? Other?
