Ok so im just wondering what the mileage is on some of yals suped up sixers. I'm hitting 167,000 now and am concerned with all the stuff I plan on doing should I start preparing to replace the engine? If so what recommendations do you all have for replacements? If I have to replace it I want to do it with something just as if not more powerful. Do the 2005+ engines fit in the 2000 new edge models? Also any advice on any mods you have done on the engine would be great thanks!
