I need 240 carb help!
I have a 67 f-250 with 240/ 4sp and need some help selecting a proper carb for daily use economy. Current setup is the factory load-o-matic/ spark-o-matic. I have a DUI distributor coming and was leaning to the Carter one barrel. I would appreciate suggestions. Can i keep the 1100 and pull vacuum off the manifold for the dizzy?

I have had good success using a Carter YF from a 1970 F350 with 300 engine. Any Carter YF or YFA up to 1982 or 1983 can be made to work well.
They are simple and can return very decent gas mileage.

Just watch out for different mounting pattern/ sizes. I might be wrong, but I remember not all of the 240/300's had the same carb mounting bolt pattern. If you have the 1100 I think it had a different bolt pattern then the Carter's. Just double check that before you swap carbs ( if you plan to ) .
If you want to swap carbs and the bolt patterns are different you might need an adapter or to swap intakes.
My self I'd go with an aftermarket intake Either a Offy C-series( Not the Dp ) or Clifford single 4V intake. Then add a 4V to 2V adapter and run an Autolite 2100 2V in the 0.98, 1.01 or 1.02 size range. The Autolite is a simple carb that will give you good performance and economy.
If you don't want to get into the cost of the intake swap then the Carter YF 1V would be a good choice.

The early 240s and 300s still had two carburetor mounting bolts oriented the same way, but were just a little closer to each . An earlier style carburetor can easily be modified to fit the later style manifold using a small round hand file. It takes about 15 minutes.
It is not uncommon when using a remanufactured carburetor to find slots rather than holes for mounting. This is so the carburetor can be used for either early or later factory intake manifolds.
