    I have a Motorcraft 2 brl on it that is rebuilt that I was told is a real good carb. I just can't seem to get it to stop from running rich and will continue working on it but was wondering if anyone has ideas on this and what has worked well.

    I just want a good dependable carb that is responsive but not a gas guzzler.

    Honestly they are all good when they are right. You probably need a rebuild or a re cleaning.

    I had an autozone fuel fitler issue where the glue was braking down and not letting my needle and seat, seat properly

    I would stay around 450 or 500 cfm's and if you go Holley, go vacuum secondary

    Holley has a 2300 series 2 bbl. It has a maual choke. Comes in 300 cfm and 500 cfm. I'd go with the 500 cfm. Summit carries them for less the $285.00

    Go with the Holley 500 cfm off road type----Good reliable, good milege,& not a double pumper, manual choke.

    One thing that a four barrel manifold and carb will do is give you a more even distribution of air/fuel across the cylinders.You may even pick up mileage,if you stay out of the secondaries!The vacuum secondary style carbs work great on the street,I've used both the Edelbrock 500 cfm and the various small Holley 500 cfm carbs with great success.I'm currently running a Holley Avenger,600cfm on a mostly stock 302,works great.

    If you just want sweet running and mileage, it's very hard to beat the old Autolite 4100- or even a 4300 if you run across one. Very nice idle and clean running, and dependable as a rock

    I will be the 3rd one to recommend the Autolite. Check Pony carb.?

    Screw Pony Carb...they cost WAY too much. Look at local swap meets. I scored both of mine for a grand drum roll worthy total of $75...and one of em came off a running car. Both are 600 CFM.

    They are still out there and quite abundant. The hard part is finding one with the exact carb tag that matches the build of your Stang or Galaxie. Outside of that, common ones without tags should be relatively inexpensive.

    depending on what you expect of that 289 , you probably have the best carb. in that little autolite/motocraft. Check the power valve as that can really cause a big time fat condition. If the 4 bbl. sounds better, the 4100 series is hard to beat but they are getting scarce. Stay around 450-500 cfm max . I have a 67 bronco with the stock 289 and an Autolite , works great in all off camber off roading and has for the last 35 years weve owned it.

    I have an Autolite 4100 that came off a 63 390 if interested. 75.00 worked when I took it off.

    4100's are great. I believe the 1.08 ven is the 480cfm which was the standard 289 4bbl and the 1.12 ven was the 600cfm which came on the hi-po motor.
