Well, I'd say run, don't walk from the 2003 6.0, it took them a while to sort it out. The 7.3 never did get sorted out, the cause of cackle and knock was the way Ford dead-ended the fuel rails without any way for air to return to the tank, it stayed in the rails until it went through an injector. The Navistar 444 had a pressure accumulator on the fuel rail, and excess fuel went through the rails in the heads and back to the tank.
