[Supras] numbers on block

Bill:

    The numbers stamped on the oil pan flange refer to bearing sizes, 
main bearing sizes if I'm not mistaken.  A JDM which I refreshed also 
had foru 2;s.  There is another number near the oil pressure sender with 
a "7M" followed by maybe 10 digits.  That is a serial or date number.
