1984 Ford F150 Carb help please

I have a 1984 F150 with a 300 straight six, 4 wheel drive and manual transmission. My question is which carb to put on that will give me the best mpg. Right now I have the stock single bbl on it. Power would be nice, but I am pretty easy on the throttle. I have heard that weber makes a good carb but you need to replace the manifold. Is this true of all 2 and 4 bbl carbs with this truck. I appreciate any help. Thank you

Have you converted this truck to a duraspark II distributor and ignition system? Do you know this engine was more than likely computer controlled? The absolute best fuel mileage from this engine is keeping all the original computer controlled system in place. If stuff has been taken off, and you still have the original distributor, your fuel mileage will jump way up by just fixing what was broken by taking smog stuff off.

This particular engine throws everyone a curve when they encounter it. Most people jerk stuff off a older engine like this and drive on, but you can't on this setup.

Thanks Dave. I have not done any conversions to it yet. It sat in a junkyard for a very long time and needless to say a lot of love has been given to this truck. I know the smog stuff was removed. There are a lot of wires that have been disconnected (temp gauge, oil pressure, etc) so I am sure that if this truck was computer controlled, it was removed long ago. Does the duraspark conversion rely on a computer or is it self contained? I appreciate your response. Dean

Dave is right - as always. Best would be with the computer controlling everything. But if the computer has been removed it would be hard to put it back, and probably not worth it. However, it is rare that people removing computers know what they are doing, and it is probable that they did a half-way job.

A DS-II system needs no computer. And the stock carb and a DS-II system will give you almost as good of MPG as the computer.

Can you get into more detail on your carb and intake setup? Did you buy the carb already tuned for this engine or did you buy a universal one and change the jets? If you did, what jetting did you use, and what is the timing set at. Did you use the duraspark II as stock or did you mess with it any?

Good questions! If we had answers to those, and similar, questions we could have a neat database that might answer a lot of questions that keep coming up.

This week I have been searching for a Weber solution for a 300-6 and particualarly a progressive one. Not really for fine tuned racing but for daily driving with reasonable mileage. I know Clifford offers Webers but they seem to be geared more for all-out racing?

Keenly interested here in this solution..thanks for letting me butt-in.
