fordcummins.com is another site that you can check for stuff on the conversion. i dont know the cummins is a great engine with big time potential. i know the 7.3 is also a good engine. and dodge doesnt own cummins they were just lucky enough to get the contract. it would have been nice if ford wouldve hooked up with them along time ago instead of international because they wouldnt be in the BIND they are right now..
