Decades ago (back when I was still a puppy), I observed that GM and Mopar had the same firing order. I also noted that GM and Mopar numbered their cylinders with odd numbers on one bank and even on the other, however Ford (wisely) numbered their cylinders 1, 2, 3, 4 on one side and 5, 6, 7, 8 on the other. So, I set down and figured the Ford firing order, had they numbered the cylinders the same as GM and Mopar, and guess what. Yep you might have guessed it, it was the same order. Now I'm no longer certain which Ford engine I was looking at, but I think it was the older 15426378. So if you remember a Chevy firing order, you can wire your Ford FE, if you call the cylinders the same as a Chevy.
Hope that helps, Ernie.
