No! And one off of a 302 won't work well either. The venturis are too large
There were allot of 2.8L engines with non-feedback carbs. I bought mine at "DA ZONE" for $169. I told them I wanted the carb for a 1983 Ranger 2.8L. The feedback carb was introduced in 1984.

Any carb from a 2.8 from 1983 and back is what you are looking for.

Also, an option.

When you switch to the Duraspark distributor, consider using a GM 4 pin ignition module (HEI) and use your TFI ignition coil (the square one). The wiring is simple and available online. You'll save some money (GM Module is $8 plus no need to buy a coil) and get a much hotter spark then with the Duraspark module and coil.

I performed the above modification to my 1984 Bronco II.
The required parts were:

* New Duraspark Distributor (1983 Ford Ranger with 2.8 Liter V6).
* Ford 2 barrel non-feedback (not electronic controlled) Carb (1979 Mustang with 2.8 Liter V6).
* Ford TFI style coil (Accel or MSD is even better). The square one.
* GM HEI 4 pin Module (1978 Camaro with 350 V8).
* Piece of steel or Aluminum to mount module too.
* A fist full of wire.

If I can find the pics, I'll come back and post them here. I did the conversion in 2004 and I can't figure out who's server hosted the pictures for me.

A 2.8 V6 in stock form only pulls 269 CFM volumetric efficiency a full throttle, that carb will most likely be too much for the 2.8. Check the metal tag on it and have the auto parts guy cross reference it for CFM, most likely too much having been on a 351m.........Try to limit your search to only 2150/2100s that were on a 2.8 or a 302.

Relay clicking, feedback carb... well, there are two thoughts on this: Replace the bad parts of your feedback carb / EEC-IV setup or do the duraspark / non-feedback carb swap. The only problem I see with the latter of the two: It all depends on how **** the emissions tester ****'s are. I just know that Federal law pretty much states that 'if it came with the vehicle new, it has to be there'.... so, that will be up to you. I'm almost willing to bet the clicking relay has to do with your idle speed control on the carb, but what exactly is what, I'd have to look into. Hope you get 'er fixed, RONEV and others....

Sounds like your TFI module on the side of the dist. has died................All the more reason to Dura-spark it and be done with all its troubles.
