Thanks for the pic, Fox. That's what's in the '82 shop manual (minus the color and 5.0 HO label on the bottom).

Thanks, guys. The thing with Chilton and Haynes, they show both HO and non-HO for the 1982 5.0L motor. I don't have that '82 shop manual, will have to look for it. I have one for the 351W HO Vic I've got, so I know their value.

With the engine work that's been done to my car, would it not run rough if it were wired incorrectly? I've driven it several times. I'm going to be changing out the battery cables and need to get the new belt on, so I haven't cranked it yet after the tune-up. I know it works with the non-HO firing order, so with no replies while I was under the hood, I wired it back up that way. Haven't got a chance to touch it since.

I guess my question is this: what reason would there be to have wired the motor up with the non-HO firing order. What would have been changed in the motor to require that, or is it just an oversight or confusion?

Thanks.

The camshaft dictates the firing order. If your engine runs on the 154... firing order, either the camshaft has been changed out or the whole engine is from a vehicle that did not have a H.O. engine.

Not every 5.0L engine was H.O. From '82 through '86, only the Capri/Mustang 5.0L was H.O. The 5.0L engine in all of the rest Ford passengers cars in those model years was S.O.

S.O. = 15426378
H.O. = 13726548

You could figure out if the block is original if you got the VIN off the top rear.

Hmmm, got me curious. I'll look for the VIN in the morning and post the results.

Were you able to verify if the engine (block) was original to the car?

Not yet. I looked but wasn't able to come up with anything concrete. I want to clean the block more and bought a box of Crayons to try to fill in the numbers for easier reading.

I did look over the paperwork on the motor more in depth. What I thought was a receipt and warranty for rebuilding it now looks like an outright purchase of a rebuilt motor.

They used the 351W cam from '73 passenger cars IIRC in the '82 HO motor. My uncle had an '82 Capri 5.0 4spd that ran awesome but scrap got high and he crushed it due to rust. What a waste.
