Can anyone tell me the difference between a Motorcraft 2100 and the 2700 carbs, other than 600. Will this work on a AMC 304 . My carb is junk and I could do a rebuild or replace it with a new 2700 that's knocking on my door.
I think that is a variable venturi carb that Ford used. I think it has the same flange pattern, but I have no operational knowledge.

You just keep proving me wrong LongHorn 
If the variable venturi carb is a 2700, that is definately not what you want plumcrazy.

Spent a little time researching the Ford Variable Venturi carbs. There are 2700 series and 7200 series Variable Venturi carbs. However, no one had anything good to say about these carbs. They were Fords attempt to make a carb/trottle body injection hybrid before they went to fuel injection. They are apperantly overly complecated, difficult to work on and difficult to keep tuned correctly. They were found on Crown Vics, Mustangs, and some F series pick-ups. Again, LongHorn, as long as you're around I'm going to have to triple check my info .
.
Im pretty sure I have what you need. What venturi size? I'll grab a pic when I get home from work.

Great info guys, I think I'll just rebuild my 2100 for now, until I can find a good deal on a 4 barrel set up. Thanks
