Gary, one thing to consider is that while the motor you've found is a "BIT" cheaper, you probably really don't know anything about it. If you have yours rebuilt for a "BIT" more, you will know exactly what was done.
DON'T EVEN THINK OF NOT REPLACING THE OIL PUMP WITH A NEW ONE.
I guess what I'm saying is that I would rather have the work done than take someone else's word that the work was done....
Doubt your old engine is worth much but might be worth a few bucks to another Dodge owner looking for spares.
