MGA Blocks

[Bill <wbmcleod@cox.net>]

I have 3-4 MGA bare blocks which I will be putting up for sale on ebay 
shortly, and I have absolutely been unable to find the stamped ID number 
on the center main bearing cap.  Could anyone tell me where to look?  I 
really hate to have to sell all these as possibly needing line boring, 
just because I can't find the stamped number.  TIA Bill
