My 03 Dually which has served me well spun a bearing & poked a hole out the side of the block. As I use my truck lots in the summer all I could find was an 06 which is in great shape great price.. I guess the easy thing to do is build it as an 03. I can put my injectors in with all my wiring harness. My only thought is my 03 has a throttle cable & the 06 has fly by wire. Is there a way I can get around this? Thanks

 

Here is a recent thread where a 2006 Cummins engine was dropped into a 2003 Dodge truck.
