    I've been thinking about it....with a Motorcraft 2100. They are one of the best carbs ever imo as far as dependability goes.

    I think with the 250 hood clearance is tight. I put a Pinto type 2bbl on my old 300 in my '75 F100. It idles much smoother and the extra "kick" is similiar to a 4 bbl kick on a v8. I like it, but it seems to use more gas than the old 1 bbl.

    I did it a few years back on my 65 Falcon with a 200. I swapped a Duraspark dizzy at the same time. It was the best thing I did to that car. Better throttle response, mileage, and power. I'm getting ready to do it again on another Falcon 6. The adapter was $45 from Summit.

    If you want to get the most from your two barrel swap use a 2Bbl to 2 Bbl adapter and have the manifold cut to the same oval opening as the adapter. Putting a 2Bbl on and keeping the round hole in the manifold won't increase the flow much at all.

    Yeah I've heard all of that before....but I don't plan on running my 250 inline 6 in the NHRA.

    You might as well just put a single barrel on it then - the hole in the manifold can only flow so much air and putting a larger carb on it is the same as running a four barrel carb on a two barrel manifold.

    what if i didnt cut the manifold and just use the adapter (i know your going to tell that thats just like running a 1bbl) but could it possible work?
