    That is very fortunate that both the 5.5 and 6 hp during that many years can use the same piston . The crank rod journal must be a different diameter, is why Mumbles said to use the rod from the motor, just swap the piston out. Is that correct? Cause the 5.5 have bushing type rod bearings, the later 6hp had needles correct?
