I  noticed something weird on the main bearings.
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!

Thanks,

Eric,
This was standard Corvair practice at the factory. Many engines came this  
way. Apparently machining tolerances on the crankcase were such that this was  
done to get proper clearances for the crank journals.
