Hell, that's just like asking why they discontinued the 5.0L, the last 10 years of that motors life it became one the most popular and longest lasting engines out there. I had an article from mustang monthly, they where working on a 1991 Mustang LX it had 210,000 miles on it and it was still putting 192hp to the ground stock. That is a heck of a motor, I've never heard of a chevy motor doing that.
It's also pretty sad when you see chevy making big power with pushrods and ford making comparable but expensive power with mod motors.
Their making big power, but their not making as much torque as the Fords are. The Fords have a shorter stroke than Chevy does and that's why Fords take'em off the line and in the quarter, but not on the top end.
I have heard of the F100 getting the 3.8L v6 very early in the eighties, supposedly a guy near my parents. As for seeing it in person, never did see it in person. My Hanyes manual for the F-series from 80 to 96 does have a section in it for the 3.8L V-6 in it.
I had a look thru the forums and a 3.8 (Essex)V6 was in some F100's in the early 80's. I guess they had aluminum heads and had problem with head gaskets due to the differential heating of block and head.
I'm looking at the section for the V6 in the Haynes manual chapter 2 part C and it does not say anywhere on the page that they were in use in the F100's or the F150's. I would really have to see it to believe it and that's only if it came with the factory manual stating it came from the factory that way. Not trying to be a kiljoy, but I just don't believe they made them from the factory that way.
i have also read about the 3.8 in some pretty reliable sorces such as haynes or that type of book, being in older trucks. probably one of those things that 3 of them were ever made, and all three are probably in a cube some were.
Ford has consistantly made engines that provide more low rpm torque then anyone IMO. and ussually with a smaller over all size. 302 vs 318 and 305. 5.4 vs 5.7 and 6.0.
the 4.0 was first release somewere around 91 or 92 in the ranger and explorer and remained unchanged till 97ish. they went from pushrod to sohc and has not changed since, they offered both versions in the ranger and explorer for a year or two and now they are the base mustang engine.

"The new Essex V6 was added in 1982, but dropped after 1983 and the 300 inline six continued as the standard engine through the series." copy'ed directly from that website under 7th generation
Well ahhh, I guess we just got schooled, I read the article and I'm big enough man to admit I was wrong. Just never heard of them putting a V6 in the F series trucks. Boy I bet if you could find one today in pretty good condition it'd be worth a little bit of something.
80-81, F100's had the 255 V8 optional, 82-82, the 255 was replaced with the 3.8 V6, making the 300 an optional engine. Being only 112 hp, and having meidicore torque(I think 180) the 3.8 was no exactly popular, especially considering F100's of that era usually had 3.00/8 or numerically lower gear ratios.
As for the 4.0 Cologne, It's found in Ranger based vehicles, Ranger, Explorer, Explorer Sport Trac, Aerostar, and the 05+ Mustang.
Other than the newer OHC engine compared to the older pushrod version, I don't think there's any real big differences to be found other than maybe some computer tuning..
