The 400 in the 1979 F150 has a 2 barrel carburetor , so unless your willing to change the intake manifold to a 4 barrel manifold and get a 4 barrel carburetor , I would stick with original equipment

I believe that the carburetor type fuel/ air ratio delivery system was replaced by Fuel Injection, no carburetor to the best of my knowledge.
depends on the use and internal components of the engine.
Try to find an older mechanic that has experience with your brand of carb and knows how to rebuild it properly.
That's typically caused by a worn "needle and seat" assembly. You can purchase a needle and seat assembly for a specific carburetor, but it's best to purchase a rebuild kit and do the whole thing.
this is the same in an older car. fuel is injected into the venturi, mixed with air, sent to the pistons, and- you are no longer working with carburetors. it is best if you research a car's carburetor.
Rochester Quadrajet 4-barrel is a real good one if its built right
you need to give more info!!..example what are you going to do with the 460?..race it?..pull a boat?..ton truck??
Start with adjuster screws about 1 1/2 turns from "seat" and turn about 1/4 of turn at a time either in or out until best idle.
I would try Pony Carburetors. They have a website, and are the best Ford carb people around.
The Buffet Moening barrel, best suited for the R13, is a great barrel that helps focus the tone and improve intonation
A lot of people have a tendency to over carburet their engines. If this is not a high horse race engine and more of a pickup truck or mild hotrod motor you may want to try sticking with a 600 or 650 CFM carburetor. It really comes down to the details. What type of vehicle and its intended use as well as the engine specifications. Ie.. Cam, heads, etc
