The large radius do add strength to the crank and as long as you can"fit" the bearings and set the rod side clearence it is not a issue of concern to me.We fit the crank by scraping the main bearings and the crank end play was checked and were in spec.It came in at .006,.004 to .009 is acceptable.The crank will be corrected for the runout.We have not decided what to do with the rear flange but will make a decision after we check the balance.
