I was told it's at least .030 over. They make everything over bore. It could be 30, 40, 50 or 60. They don't even stock standard pistons. My brother in law used to do insurance work.
I'm sure the crank is probably cut also, but they do know how to use a torque wrench, even thou the guys doing the work are very very low paid.
I wouldn't waste time & money taking it apart. It's fine for driving around at normal RPM.
