Let's see, standard bore is 3.375 so .010 over would be 3.385
The circumference of the +.010 bore is 10.634 and the standard bore is 10.603, a difference of .031
I would say somebody was completely clueless on proper gapping techinques and just plain screwed up.
Did you use the piston upside down to make sure the rings were square in the bore?
