    crankshaft identification

    As much as I hate to appear to be a retard, :? I am going to have to. I have limited information for big block id purposes. I have always been a sbc guy, ready for more cubic inches! I am trying to id the crankshaft I have in one of my motors, any help would be appreciated! The crank is for a big block.

    Cast # 3856223 it has Z J K just above it, this was found on rear fillet.

    S7 X 6 + was on the front fillet.

    I will try to add picture.

    Thanks,
    Rudy
