So the 2007 was brought in from Ford with the same 3.5 block as Ford variants (Ford Edge) and then 2008-2015 is a bored out 3.7L block. So the long block is the same 2008-2015. The differences in the later (more recent) models are going to be miscellaneous fittings, retainers, clips, perhaps a couple of small tubes, but the long block itself is the same. So if you were to buy a motor from a 2010 and you found something that didn't quite fit right, just transfer it over from the bad engine (like a small tube that doesnt fit a larger tube, etc). Even if the wiring harness has differences, which it might, then transfer the harness over. Just deep cleaned my 08' with 104k inside and out this weekend, checked all her fluids, good to go. No coolant drop, and just a little low on 5w20, but it has always been a little thirsty with 5w20. Uses much less when running 5w30. The motor runs so well, no noises, just a gem! clean as a whistle underneath still too. Too bad that some folks had bad luck with a few of these motors. Although I did have a spark plug cross thread lol.
