If you mean "Cummins 5.9L" yes it's a good engine. There is no such thing as a Cummins 6.9L. The 5.9L I-6 Cummins is known as the "B-Series". It was named #10 out of 10 as the best-diesel engines ever according to Diesel Power Magazine.
Cummins is the manufacturer.
Chrysler V8, yes. Cummins diesel, yes.
Very good engine, although replacement parts are getting harder to come by.
NO.

The Ford Motor Company never bought Cummins, Inc. That said, Ford has used Cummins engines in some of its trucks.
Not entirely. Ford owns 15% to 25% of stock in Cummins. You can get the Cummins diesel in the Ford F-650 and F-750. No, Ford Motor Company (FMC) at one time held less than 10% of Cummins shares but at the present time does not own any part of Cummins inc. From my research, Cummins is an independent company with publicly traded stock.
Engine is the same, injectors and computer are different.
No, it has a sliding nozzle turbocharger not a wastegate.

Won't be an easy fit.. the Cummins is an inline six, with a much longer block. You'll almost certainly have to go to electric fans.
Cummins is good. Dodge is not. Cummins has always been a good engine. Dodge is lucky to have the contract with Cummins. I have 2 Dodge Cummins (an 1992 and 2006). Both have electrical problems and the transmission in my 2006 isn't great and that's with stock power and only 93,000 miles. The 12-valve Cummins is all mechanical- easy and cheap to get power out of it. The 24-valve Cummins is computerized- have to buy a programmer. The best combination would be a Cummins in a Chevy.
