well he would have to pul the oil pan and back main cap to check runout on seal face as there not much hanging out of the crank hub . alot hubs are back angled so very hard to get a run out check on it from the out side with pan on .i look at a ford at the shop to day and a scat crank out of a 351 fly wheel holes should be blind there alot of meat there so someone would have really gone at it to brake thru .still good to check it. as for checking run out there is about 3/4 of hub hanging out of the back of block so if you hanged dial indicator with a very long extenion a foot or so . to thread in the dial indicator tip so maybe it could be done so cffisher was right it just would not be very fun job you first need to make up a extenion that threads in the dial and watch the weigth of the extenion as this will move the gauge
