Hello, I have a 2006 Pontiac Grand Prix GT and it is coming up on 200k miles pretty fast. I was just wondering if it is at possible to swap in a 5.3L instead with no problems.

read this article. Based on this and other questions about the same conversion you need the engine, the transmission, possibly the subframe, and all engine electronics and wiring. Not worth the effort.
