7. 1928 Harley-Davidson factory experimental FHAD,
In 1928, H-D modified OHV Peashooter heads and cylinders and mated
them to an FH racing crankcase, creating an OHV 45 cubic inch engine with
which to contest the professional national hillclimb championship. This experimental
hillclimber was not successful in overcoming its competition. The historian, Herbert
Wagner, has noted that this factory-experimental OHV engine served as another
precursor for Harley-Davidson's OHV production big twin that was introduced in 1936.
This example is complete and correct
in every detail. In addition to the beautifully constructed OHV FH experimental
engine, this machine exhibits the rare 3-bar hillclimb racing chassis that was
modified in the H-D factory to accommodate the OHV engine. This machine is
exemplary of H-Dís race engineering and is considered the better of the two remaining
examples of this rare specialized model.
