Thanks Kas!

In as much as the particular engine is all standard bore, and crank
journals, I didn't figure it had been touched since it left the
factory.  

But I guess anything is possible.  At lease I'm reassured that I won't
have to worry about special consideration for a weakness in that
particular area!

Thanks again,
Joe
