I know they upgraded the engine to make more power at some point, and I believe it was 2008. They added a second bank of plugs and some other stuff; I want to say yes, but you're also dealing with 2 separate generations of truck so the controls and electronics may be different
Thanks for the reply. Not sure what to do here. The salvage yard said the 08 and 09 were compatible. The 08 4.7l engines I found on ebay when I plugged in my 09 truck in the compatible chart at the bottom of the ad it said they were not. Looking for some verification this will work as I can only find an 08 engine.
that is the same list I have seen... take a look at the intake... the older ones that won't work are magnums... Im actually in the same boat... I have an 09 and putting in a jeep 08 4.7 motor... they are compatible
