Oldsmobile 70 442 455 4sp crankshaft #397363 with big “N” for Nodular. I have had this crankshaft saved for over 35 years. The engine threw a rod and the crank got a large score in a journal which needs to be repaired and re-machined. View the pic showing the large deep score needing repair. This crankshaft is rare because most Oldsmobiles were automatics which don’t have a pilot hole. Therefore, to have a 4speed olds, you must have a 4sp crankshaft. This is pick up only, sorry no shipping.
