The 6.4 engine was the first to have the diesel particulate filter (DPF) that would inject diesel from time to time into the catalytic converter to burn out the exhaust. You just need to be careful not to be in a hay field when it regenerates at 1000 degrees.
The 6.4 was a strong and somewhat quiet engine. The only real problem with it was the fuel mileage. The newer generation 6.7 liter Ford built engine gets better fuel mileage, and is even stronger.
