Work with your machinist! You have to know what specs YOU want, DON'T count on the machine shop to know. They work within 'acceptable' ranges for grinding the crank or boring the block. If you want .0025 rod clearance you need to talk to your machinist about it before he grinds the crank. It's common for a machine shop to bore 'standard' sizes as well, .010, .020 etc. But what if it's a side oiler, you may want a .017 overbore and a final hone might get you .018 or .019. These 'odd ball' sizes require a little more than just another 'grind and bore' coming through the shop. THATS another reason to go with an experienced FE builder.
