I'm in the process of building a 292 with a steel crank and my machinist has a concern about the radius area where the journal meets the throw. Radius is a little tight or should I say a sharp angle. For a performance build should the crank (which is a useable standard) be ground .010" and have more radius built in?  Better oiling? Would a better route be a nice polish and go with a .001" bearing? All opinions welcome. Thanks.
