Where did you find that gibberish.
I've worked on GM 2.8s and I'm familiar with the Ford 2.8. Pretty sure they aren't the same engine.
The Ford 2.8 was an evolution of the Tanus V4. The GM 2.8 was a similar 60* push rod engine, but the Ford 2.8 was a clear evolution of the Tanus and Cologne engines, its not a GM engine.
Well, wikipedia lists the 2.8 chevy here:

It's also here:

Here is swappinng from a 2.8 to a 3.4

Specs on wikipedia:
LR2
The longitudinal LR2 was a truck version ("B-code") produced from 1982 to 1990. It used a 2-barrel carburetor and produced 115 hp (86 kW) and 150 lb·ft (203 N·m).
Applications:
1982-1986 Chevrolet S-10/Chevrolet S-10 Blazer
1982-1986 GMC S-15/GMC S-15 Jimmy
1984-1986 Jeep Cherokee
1986 Jeep Comanche
As for the Motorcraft carb thing, I heard that one a long time ago, and knowing how cobbled the AMC's were (an AMC Eagle has a Chrysler 3spd auto but the Jeeps like my dad's Grand Wagoneer had TH350's behind the 5.9 - go figure) I didn't really doubt it. Looking all over the internet at part sites, though, they list a 2bbl Rochester as a replacement. Sorry if I confused anyone- I'll retract the Motorcraft carb comment.

The reason they used the 2.8 was it shared a bell housing with the 2.5 I4, and the price was probably right. the fact it was dumped in about 2 years and they shoehorned their own 4.0 in shows what even they thought of it.
