Troubles taking a 360 .060?

How do you "offset" grind a crank and come up with stock sized 360 main journals?

It has nothing to do with the mains! The rod journal is re sized from 2.125 to 2.000, with his math that even has left an 18 thou margin to do the off-set. this has yielded a 383.54 cid size engine.
