Transman,
Are the journals all standard or undersized?
As for that bore mark, that’s typical of water setting in the bore. In fact, in your situation it looks like you have two of those marks.
Yes, both the connecting rods and the mains are 0.010" under.
Regarding the cylinder wall mark, I'm thinking whatever coolant may have leaked through would have then settled around both the 1st and 2nd rings...probably even down to the oil ring as well?
That makes sense since the mark is on the outer block side that would have allowed the coolant to pool there.
