Neither. If you can find one, the Autolite 1101 is a 1.29 Venturi carb that out performs any Holley 1904 or 1.315 Carter YF or YFA. You have to make sure the throttle blade clears the intake hole in the manifold.
The anti-trust war between FoMoCo which owns Motorcraft, and the formerly Presolite, who were owners of Autolite before Ford went for a purchase....that patent dispute between 1961 to 1970 had far reaching issues for the carb production, not just spark plugs.

The case prevented Ford owning all of the 1 bbl Annular Discharge technology. So the Holley 1940 was used as an Autolite 1940 and then Motorcraft 1940 replacement for the Autolite 1101 on the 240 and 300 Big Six, and then some of the early 250 1969 sixes.
The two year only 1bbl 1101 uses a Ford F jet, annular Discharge Venturi, and it's not a Pony Carbs rip off. The various sizes1904/1908 Holley's, always a work in progress, the Holley 1940, never a good carb as it had different venturis and and many changes from 1969 to 1975. The Carter YF and YFA, a metering rod carb, so it administers fuel in small droplets, so it's a pure economy carb.
If you can find an Autolite 1101, or if you can service the plastic Venturi which they had, you'll love it with a two diaphragm ignition.
1101= Autolite Non Load-a-matic 1bbl carb. The Autolite 1100, Load-a-matic, and not the same big Venturi as the 1101.
If you can't track down an 1101, then use a Carter YFA with its bolt holes slotted, and open up the intake manifold to clear the 1.687 inch throttle.
