I don't think you have this right. Any power increase from putting in a 180 stat is from the fact that the ecu will add more fuel because it sees the engine below operating temp. Relocating the IAT does the same thing...it fools the ecu in to thinking the air is cooler than it is, thus the ecu adds fuel to adjust the fuel/air ratio. The 160 temp stat with an efi engine will usually cause it to add too much fuel and you'll have driveability problems. I don't see any problem with going to the 180 stat on a 4.7L. I installed a 180 in my brother's 5.2L without any ill effects.
Not to offend you but I think your language could be misleading here. Relocating the IAT doesn't "fool the ecu" it allows it to correctly read the air temp.

This is why Dodge moved them on the 2003 and later vehicles.

As far as the 180 stat goes, I've heard good and bad. either way I think the 4.7 needs synthetic. At least I sleep better knowing there's synthetic in mine.
