just pulled the motor out of my f-150 to change a bunch of things. turns out i need to rebuild the bottom end. the guy that was checking it over said that they went with a windsor firing order in 94. i checked the cap and instead of it being 1-3... , it is the 1-5 order. my build date on the truck is 11-93. does anyone know if they started that halfway through 94 or should i be taking a closere look at this. the motor is not an original and it doesnt look like any of the injector plugs were switched.

 

According to my book the firing order is:

5.0L and 7.5L enginesFiring order: 1-5-4-2-6-3-7-istributor rotation: Counterclockwise

It doesn't mention any other possibilitie for the 5.0. It does list the 1-3-7 firing order, but that's for the 5.8 motor.
