    1940 ZEPHYR 292 CU. IN. V-12 CRANK SPECS..???

    Does anyone out there have crank tolerances (miniumum & maximum) for the 1940 292 CU. IN. V-12 flathead engine..??

    I also need the 'housing bore' specs for the big end of the rods.


    Would greatly appreciate the help.

    Thanks !!!!! However, bearing/thrust clearances are not my issue... I need the minimum-maximum Crankshaft Specs that I might find in an OLD Clevite book.. I also still need the housing bore spec for the big end of my rods, as well as the mains.

    I have a FoMoCo shop manual for this engine already...
    Thanks, justin.
