                The original stock firing order is 1,5,4,2,6,3,7,8.

The original stock ignition wire order is as shown in the Shop Manual, Section B, pg. 71 – 7-5-6-8 for the left side.

 

In general the majority of engine related pictures, diagrams and wording in the Sunbeam Shop Manuals are directly from Ford Shop Manuals.

I recently decided to replace my plug wires with a new set that has the correct OEM markings.  As simple as this process sounds, it turned into a great adventure for me.  I won't relate all the details of the adventure but there was a question that arose that I hope someone can answer for me.  The shop manual contains a drawing that shows the correct routing for the plug wires.  On each side of the engine the wires go through a couple of wire guides that provide the correct spacing and routing for the wires.  On the right side the wires are routed in the order 1-2-3-4.  On the left side the order is 7-5-6-8.  The text in the manual explains that the reason for this order is to provide separation between the number 7 and 8 wires.  Seven and 8 are adjacent in the firing order and routing their wires in close parallel as they would be if the routing order were the expected 5-6-7-8, might lead to induced current between 7 and 8 resulting in misfire.  I routed my wires according to the advice of the shop manual.  My question is, was the original (factory) order 7-5-6-8 or was it 5-6-7-8?
