Should I swap my 3.7 for a 4.7, a 5.9, or modify what I have?
My ‘08 is the first and only vehicle I’ve ever had. My goal is to turn it into an even more beautiful piece of machinery than it already is. I’d like to keep it as stock as possible, but make it as bad@$$ as possible at the same time. Is that achievable?

Well if you end up swapping your engine, you will need a new wiring harness among many other things. I'm pretty sure the transmission that comes with the 3.7 is not compatible with the 4.7 or 5.9 either. Someone please correct me if I am mistaken. I've had a couple 4.7s and they both were great, but people have had issues with them. I don't know all too much about the 5.9, but I always hear they are reliable.
