Is anyone running a 4.7L???

I worked in the auto salvage business from 2005 - 2012 and would recommend against it for two reasons. One being they have shown to be a problematic motor. Like most mentioned they sludge up and kill them selves. Our old joke was if its a Chrysler and ends in .7 avoid it (2.7, 3.7, 4.7) with an exception made for the 5.7. Now that's not to say there aren't several people with these engines that have served them well, but most don't. Second reason being cost, at that time we were selling these 4.7 engines used for $1000 - $1800 depending on miles, we were selling 5.2 magnums for $300 - $500 and 5.9 magnums for $400 - $600.
