2007 into 2003 truck

Just wanted to know if anyone has done this. Also, if anyone has some information on how to get the 2007 ecm to work right with the 2003 truck. Both motors are 5.9's. Both trans are 6 speeds. Both Transfer cases are manual. I'm sure there is a thread out there somethin like this, so if you know of it, please send it my way.


Thanks.

You can do it. Injection events will be different so not sure how that will act but physically it will work. Also piston and injector nozzles are different.

ill gladly donate my pile to place on that 07 frame :rockwoot:

nooo... i've got a complete 2007 motor i wanna put into a 2003 truck
