I don't have the reference handy, but Kas Kastner once wrote that he
measured 5/8" of runout at the edge of a TR6 flywheel, apparently due to the
crank bending at high rpm. Don't recall the rpm at the moment, but ISTR it
wasn't a great deal over factory redline.
Ken Gillanders also once wrote of filming stock 5/16" TR3 pushrods with a
stop-motion camera, he said they "looked like dancing spaghetti".
