What is involved in replacing a 5.2 with a 5.9

I bet you could do nothing except change the flex plate and it would fit and run just fine. "Might be" that the TB is larger bore, don't know for sure, and computer/ injectors different.

Thanks, I'm trying to decide weather I should find a 5.2 or if the 5.9 would be doable without to many headaches.
