300 Carburetor

Just curious. My '83 F-100 has the original style reman carb (The 1 bbl Carter YF, I think, is what it is, someone correct me if I'm wrong). My question is: what new or aftermarket carb could I get to get better fuel economy? Or more power? I'm really not sure what direction I want to go, yet. If you find some carbs that would be good for either use, post the link for me. Or better yet, if you could post some links for both, just do that. Keep all the options open Also, on a carb, for fuel economy, is it better to stick with a 1 bbl or go to something else? I'm new to working on vehicles, so any info about carbs would be great, really.

Would this carb work? What would be the benefits/drawbacks?

Many of our forum members lean toward the use of a 2 or 4 barrel carburetor with either an Offenhauser or Clifford aluminum intake with regard to enhancing performance. They will also tell you about using the exhaust manifolds from a 1987-1996 fuel injected 4.9L, a H.D. exhaust manifold [used for large trucks 1965(?)-mid 1970s] or tubular headers. All of these are freer flowing than the stock "log" manifolds.

My conservative opinion is that if one REALLY wants to get the best mileage [rather than greater performance], you should stick with the original carburetor and embrace this engine for what it is... tough, economical, easy to service and long-lasting. Learn to drive economically and perhaps invest in an inexpensive vacuum gauge to help you learn the sweet spot of this engine.

If you really want performance, a V8 is the less expensive way to go.

By the way, I love these engines and do not want a V8.
