your firing order is correct, from what i can tell your is shifted over slightly CCW.
i'm going to say your dizzy is installed one tooth CCW and your cap is having to be in that place to get the number one terminal over the right position. or that your wires are shifted over one terminal.
FWIW the dizzy orientation doesnt matter, you can stab it wherever you want, just make sure the wires line up on top, some older cars can turn the dizzy really far either direction.
if you had nothing for th dizzy to hit, you could have number one be at the 6oclock position if you wanted.
but a 5.0 HO has the TFI module sticking out, so you cant really adjust it too far in either direction. when i stab the dizzy in my car, i get the engine to TDC on cyl 1, then i stab the dizzy and make sure the rotor is pointing around 11 o'clock
that puts the TFI module in the middle of that open area where it sits.
if its running fine which i assume it is, i'd leave it alone, if you want to change it, just unbolt the dizzy, and lift it out until the gears unmesh and then rotate the rotor an inch or so CW and then restab it.
if your wires are also shifted over CCW one terminal, then pull them all over and rewire them one terminal over. if your whole dizzy was rotated over to make it right (TFI modules closer to hitting cylinder head. then just simply rotate the dizzy to line the terminals where they should be.
