I would suggest checking with PPP, they would know for sure. I would guess that at the very least the PCM and TCM would have to be re-flashed for the 6.1 and the injector pulse would have to be modified for the stroke. Headers and 2.75"-3" exhaust would probably be a good fit also. I would be curious to the cost when you get a handle on it. You might want to price a new rear end and half shafts too.
