Ryan,
... ... I am now woundering how many parts are common between those engines and ours?

The "B series " ( 3. 9 and 5. 9 ) engine was a joint venture between Cummins and Case. Some parts are used only certain models (like Dodges ) but the basic parts, bearings gasket etc are common. In alot of cases ( pardon the pun ) you just drop the 3 from the front of the Cummins p/n and add a J. Cummins can't break down a Case serial number for example. Shadrach
