    A 3.5 is not a 3.4 so I really doubt it. Also the Computer will go crazy because it will assume that the engine is a 3.4 liter when it is a 3.5, so all the sensors will be reading incorrectly. This is touchy stuff. Is not the 3.5 and over head cam motor? I know the 3.4 is a push rod motor. this is a huge difference as well.
