The comments about making the engine swap have been interesting. The rest not so much. I have considered putting a Cummins in a 2011 F550 4WD because it eats turbos. About 20K miles and five turbos. Now there are metal shavings in the oil. Getting rid of the truck is not an option because it is serves a special purpose.
The mechanics and fabrication are less of a challenge than the electronics for me. For that reason I was thinking a donor truck would be better than just an engine swap. A 12 valve would obviously be easier but the donor truck should have all the electronics regardless if it is a 12 valve or 24 valve.
Then there is the emissions thing. I am thinking Dodge went to DEF system about 2008. The re-gen system might have been before that.
