Rebuilding a 270. The machinist tells me .030 over will clean it up good. Now for Pistons. The stock bore for a 270 is 3+25/32. Can someone tell me what the new bore diameter will be in inches?

It should be 3.811" 3 25/32 is 3.781" add .030 and you end up with 3.811. Thank goodness for calculators!
