I am getting close to having to make the exact same decision as you. For me it will likely be next year.
There is no doubt I would prefer, hands down, to put the cummins in. Better MPG, more room under the hood, major "cool" factor.
With this comes a cost, I expect that a 6.ohoh can be built reliable and installed at the $6K range where as the cummins swap will likely be in the $12K range.
So it it worth it? That's the $6,000 question I haven't answered yet.
The one thing I do know is eitehr option is better than a new truck, I am not getting into DPF, eurea injection, etc. No way.
The one thing that could reduce the price gap is the purchase of the cummins. Buying a complete write off dodge and selling off the leftovers might reduce the cost significantly. I found an 05 for aprox $7K in the US that was hit on both sides of the cab. front clip box and all running gear was fine. There would definitely be some good salvage $ in that truck once you pirated what you needed for the swap.
I wish we lived in the same town, this could be an interesting project to do both trucks!
I don't have a ford tech on tap but I do have a friend that does most of the advanced work on my truck. He has completely rebuild a transmission in my truck, done front & rear diff's and he does it right in my garage. A very talented guy. I expect he will be helping me with my swap when the time comes.
Keep us posted on your decision and progress!
