...I agree with Steve! You don't BORE for Larger Pistons! You HONE to 'Cut the Glaze' and to the VERY Next size of Piston. Should Not take more than .005"-.010" Over, that's .0025"-.005" PER SIDE.

You would Bore to Correct a Misalignment, as George stated.

I have Honed 100's of Bores, By Hand! Even did the #8 on My Cleveland, when it Broke a Piston Ring and Bent the Ring Land. Just needed .002" Total, polished off and install a New, same size Piston and Rings. Can put it right at the .0002" No Hourglass, No Barrel, No Taper! No Nothing, on the Bore Gauge. Grumpi Jenkins does it in the Pits, between Races. Yes! Paying Close Attention for the Correct 'Hash-Mark' Angle.
