    I don't think, Joe,..

    ...That Freeman's motor is 93 cu. in.

    His Tedd label is for bare cases, and a "P93" wouldn't have been delivered with a Bendix.

    (And he declares it 74" in post #37,,,)

          The intake manifold is the same as the shovelhead, it should be 74ci, The intake manifold is the same as the shovelhead, it should be 74ci, but it is not decided, the cylinder volume is not large, the carburetor caliber is 40, and the injection pipe can not be replaced.

                        Cotton you are right, V-Twin Part number 55-5008 is the complete bike:
                        Our 1948 Replica Panhead Kit is an authentic style reproduction of the original. 74" V-Twin replica motor assembled and factory tested.
                        No word on what carb came with it, but I expect they put the right jets in the carb.
