Help! What is the firing order for the 1986 fuel injected 5.0? I just located my battery to the truck, and along the way I moved the plug wires. Every book and manual I look at says a different order. I am assuming 1234 is front to back left bank, and 5678 is front to back right bank. HELP HELP HELP, FAST FAST FASTTHANKS.

I thought there was only one "HO" firing order .. same as the 351w one right? Jeez now I'm thinking mine is off too. Which one would be for a roller cam carbureted 302 build .. ?

There are 2 different 6.0's the 5.0 HO has the same firing order as the 351, but there is a standard 5.0 that used the other firing order.
