    Difference between 12F and 15F crankshaft and cams?

    How can I tell the difference? different journal length, different markings?


    Thanks

    15F Crankshaft has bigger journals than the 12F.

    The cams are basically impossible to tell apart without using a dial indicator or calipers. All the markings are the same.
