Anybody ever rebuilt a 4.7 motor? I bought a 2004 Dakota 4 door, and the motor has been overheated and is locked up tighter'n a drum. I did a search, and people either love em or hate em. How far over will they bore? The rest of the truck cleaned up nice, and it will be my wife's little truck so she will leave my diesel alone....lol. I can swap a 5.3 LS motor in it as easy as pie, but who knows what I will have to deal with at state inspection time. I live in a county that has to be smogged. 4.7 rebuild advice or tips appreciated!
