Help with 2000 5.3 LS block and 2004 ECM / harness

[TrailMail]

Hey All ive got a 2000 5.3 donor motor and ive had a stripped harness and ecu for a 2004 5.3 for a while i also have all sensors (the 04 blew a hole in the side of the block) would i just need to swap all sensors over to the 2000 motor (and Throttle body for DBW) or is there something im not thinkning about? Thanks

The 2000 would have had an EGR valve and I don’t think the 2004 did, but other than that I think you should be fine. I think it’s ICT billet that makes a block off plate for it. If you have emissions where you are at that will complicate things a bit.
