This is the front of truck,

looking out the windshield

Rear of truck.
Been like this for many years. On all V-8's.

no offense fatalerrorz, but i am going to have to disagree with you on this one.... ford labels their cylinders as i have posted......
that being said, rus01, if you want another opinion, just hang tight, im sure someone will chime in soon... otherwise you will wasting your time/money by changing the wrong cylinders plug/cop.

I'll go take a peek just to see...their COP's might be that way, or someone just threw yours on, and knew how they went, in a "damn the numbers" sense, but your cylinders and COPS's fire based on the position of the valves. If your truck fired in the manner you describe, the truck wouldn't run, and/or would shake the engine apart if it did due to the imbalance...brb...I'm going to look at mine.

Here's a quote I found...Bizzarre....
As an example, the well-known Chevrolet Small-Block engine has cylinders 1-3-5-7 on the left hand side of the car, and 2-4-6-8 on the other side, and uses a firing order of 1-8-4-3-6-5-7-2. Note that the order alternates irregularly between the left and right banks; this is what causes the famous 'burbling' sound of this type of engine. [1]
In most Audi and Ford V8 engines cylinders 1-2-3-4 are on the right hand side of the car, with 5-6-7-8 are on the left.
This means that GM LS V8 engines and Ford Modular V8s have an identical firing pattern despite having a different firing order.
I go off the firing order, and not the cylinder number. they still have to fire 1,3,7,2,6,5,4,8 while GM is 1,8,7,2,6,5,4,3...
That said, you're right...I've never paid attention to Ford being that "different" as I pay attention to firing orders.

yeah, im not sure why they labeled them in order of placement rather than order of fire. i found this out when i had a 99 f250 5.4, and the water hose leaked onto the #4 cop causing the ever so dreaded misfire.

I have no idea either...I'm glad I don't use the "numbers" to do anything; I'd be SCREWED if I did that...lol I swear, I've never paid attention and have been driving Ford's (albeit only owning 3 V-8's) since 1982. So I guess when I do a cylinder leakdown, or pressure test on the number 1 cylinder, it's really been the number 5...I won't sleep for a week now!!
