I've heard from mustangforums.com that the 4.0L SOHC is known as a member of the Cologne family of engines, which are built in Cologne, Germany. The 4.0L also has forged rods.

It's the same exact engine between the Ranger and Mustang, right? (Aside from induction and all that)

Has anyone ever heard of the Cologne engine designation before?

 

I don’t know if you could still consider it a cologne engine as it has been changed many times since its first introduction into the ford ranger and bronco II as a 2.8 and 2.9L 60-degree v6 engine in the early 80's. But yes the original 2.8liter engine was from Cologne Germany, that’s why they use all metric bolts to this day. The original cologne engine, and all models before the 4.0L SOHC, had a single cam; the new SOHC has the cam over each head reducing friction. From what I have heard though the 4.0L has mostly been bored over from the 2.8L to the 4.0L with only minor changes.

I wonder if swapping a mustang intake onto a ranger 4.0 would yield any increase in power?

anyways, yeah that is interesting, I did not know that about Cologne, Germany

 

yea i got a 2.9 and its the same thing as an older 4.0 OHV, the only real difrence is in the bore and the heads

 

You got it pretty much right on except for that little tid bit.

The only things we don't spec in metric anymore are things that cost more to purchase in metric. Now.. we model them in metric units, and use metric dimenions on prints. FEA is also done is metric. But the understanding is that it's still an imperical dimension.

Very few things are like this anymore though. About the only thing I can think of at the moment are hoses & some bearings.
