[Oletrucks] possible engine swap

[wayne osborne]

Hi guys,
  HAPPY NEW YEAR to start with...

Got a guy with a 52 with a worn out 55-235 engine and wanting to replace the
engine with as little hassle as possible and upgrade to a more modern 6
cylinder. Anyone have an idea what might be an easy swap or what engines can
he use and still keep the original tranny?  Anybody replaced the entire
engine/tranny with a more modern 6 cylinder engine?
