Again incorrect, I said number the Ford like a GM engine and start from the GM number one and you will see it is exactly the same as the LS/LQ series. Ford in red
1 5 2 1
3 6 4 2
5 7 6 3
7 8 8 4
1-8-7-2-6-5-4-3 LS/LQ Firing order
1-3-7-2-6-5-4-8 Ford 351 Firing order
Now if you start both engine on the same cylinder the Ford Firing order becomes
5-4-8-1-3-7-2-6 Oh looky it is the same sequence as the LS.
BTW that diagram does not give the whole issue, you must go throught the whole firing order not just half.

good info, but why does anyone make a 4/7 swap cam? it seems like its only going half way in sorting out the firing order.
