Better Carb.

Hey my 84 2.8L Bronco II doesn't get the best gas mileage in the world just curious if anyone has any suggestions on carb that will be better for gas. I was told to look at a 4bbl fuel economy holley. If anyone has suggestions that would be helpful I would appreticate it.

Here is what I did to my 85. I took off the 2bbl carb and but a 2bbl from a 1978 Mustang with a 302, you want to talk about being able to scream

what didi you use for a gasket? When ever I go in and try to buy a gasket for my carb it's the wrong one the gasket doesn't fit. The carb hangs over the gasket causing a vaccum problem I have an old gasket on it but it's leaking. This is the reason I want to upgrade to the 4BBL but if you can help me find the right gasket and stuff I will go the way your talking about. Do you know what carb it is that you pulled from the mustang?

I used a Motorcraft model 2100, but if you want fuel efficiency use a model 2700 Variable Venturi Carb. As for the gasket, the bolt holes are the same as the stated carbs and will bolt on. I suggest getting a roll of cork and trace the bottom of the carb you intend on using and make a gasket. Hope this helps

All of those carbs where used in 1978 so that might help narrow down the search. I have a model 2100 just sitting around here some where.

First I have to make sure that I actually have one that is not in use. Second I will need to know your address so I can calculate shipping costs Private Message me with that info.
