Good day all. Any experience or recommendations for best bearings to use on an old, maybe not so concentric, crankshaft. Mechanic/ friend has schooled me that a perfect, recently machined crankshaft can tolerate hard bearings that will last a long time without any need to conform to crankshaft irregularities. An old out of round crank needs bearing material that is somewhat malleable and can embed into the irregularities but is so soft they usually don't last as long. The old Clevite 77 bearings had both advantages of embeddability and a durable alloy. However, it seems that those NOS bearings are now unavailable I think I read that the King Bearings are the closest to them. Thanks, Arnold
