Neat old bus. Not much Info. Just stumbled across.

Those OLD LOOKS were good solid buses. I wonder what could be done in terms of a modern powertrain for that.
Since it is a Vdrive, use an Allison V730R with a reverser gear. Could use a Cummins 8.3/8.9 ISC/ISL or Cummins ISL/ISM, or even Detroit Series 50 (although hard to get parts for). Good Luck, TomC
