Hi Denny. Thank you for asking your question on Just Answer.

I have a diagram for you that should do the trick.

1996-98 5.0L, 5.7L and 7.4L Engines Firing Order: 1-8-4-3-6-5-7-2 Distributor Rotation: Clockwise.

One of the other experts just pointed out that this particular picture (above) doesn't match the firing order. So here is another diagram that does match the order.

Please let me know if you have more questions.

Take Care, Greg A.
