Jesse recently (November 2014) provided, and then installed, a complete used 2003 P71 Ford 4.6 Modular motor with 83k in my 2000 Mercury Grand Marquis. It was done very inexpensively, with no quality issues whatsoever, no rattles, leaks, loose parts or any other issues. I wasn't pressed for time (have 5 cars), so he took three weeks but I'd highly recommend you consider him for similar work.
