If it's a gasser, cylinder # 1 is on the passenger side front, #2 is right behind it, all the way back to #4 on a V8, or #5 on the V10.
For the V8 #5 is the front driver's side, going back to #8.
For the V10, #6 is the front driver's side, going back to #10.
For instance, for a V8, looking from the front of the truck,
V10 firing order is 1-6-5-10-2-7-3-8-4-9 - no idea what the V8 is
