Picked up three Schaefer flywheels for an early Olds Today. With the number WMO 601 & (either a P or F) 500 on back" with 145 tooth count..........another stamped WO 969 , F501 with a176 tooth count.........and the other stamped #486, can anybody help ID these for me, all have bronz inserts a dare NOS...........thanks
the 145 would be the early engines up to '53, 176 count would be '54 and up. That 486 might be for a 371 which was an externally balanced engine. I might have a catalog in the shop. I will see if I can find it which may prove to be a bigger challenge
