200ci Can anyone recomend a 2 barell carburator with adapter kit for my 200 inline 6 cylinder mustang

[jcom4179]

Hello, my name is Jeff and I'm looking for someone who has swapped there stock 1 barrel carburator with a 2 barell carburator and proper adapter successfully to their stock ford 200 inline 6 cylinder motor. I'm only interested in the 2 barell swap. I know all about the snipers and different 1 barell carburators. The engine runs strong and I just had 2 1/4" long tube stainless steel headers straight back to dual flowmaster 40's, true dual exhaust that truly sounds pretty much the same as my brothers 289. That's the only upgrade I've done on my 67 mustang convertibles inline 6. I did see quite a few nice looking 2 barell carburators on Amazon. I would love to know if anyone could recomend a set up from one of there 2 barell carbs and adapter plate from them. I really would appreciate anyone's help.
Thank you
Jeff

I have not swapped to a 2v carb but have read about it in anticipation of doing that and even collected several Autolite 2100 1.02 and a Weber 2v carb but recently, after reading about those who have used a Rochester 2v or a Carted BBD, I have decided to go that route. The main appeal to me is an adapter is not required and you can open up the carb whole on your existing head and direct mount the 2v. You will probably have to do some linkage mods. According to those who went this route some good performance gains were realized. The Rochester are used on Ebay and a small base version is available which is the one I want. May want to look into it.
If this link works be sure to note it was on a large log head and your 68 probably does not have a large log.

That is the exact information I was looking for. I just want to make sure I understand, can I use the Rochester on my 67 200 inline 6, which is like you said, not a large log head. You mentioned to get the small base version, right? With the Rochester 2v would I have to change the distributer. I read that when you swap out the single barrel to a 2 barell it effects something with the stock distributer. I don't know how true that is.
I would just like to thank you for the priceless information. Again that was the exact information I was looking for.
Jeff

I did exactly what you are planning to do on my 67 mustang coup. Except didn’t have headers. Remember you should really get a new distributor at the same time. You can make it work but not at best performance. At the time, I used the DUI, simple, self contained. There is a lot of info here on dizzy or check in vendor section for one set up to your needs from a knowledgeable member, Bill. He can get you one ready to go. The carb swap I did was to the Webber 34/36 from Clifford Performance. They will pre tune it for your specs. I did very little tuning after installation and drivable was greatly improved. Linkage needs to be modified but I can help you do that quite easily. Mount a fuel pressure regulator is the other added requirement, I used a simple L bracket.
You can find cheaper Webber knockoffs, but I was Leary about them. No regrets, it was a daily driver at the time and many miles put on it

My 200 has a 250 head. I opted for headers and a Weber 38 with an adapter from Vintage Inlines. Note that you should measure the inlet on your manifold (log) to make sure that you buy the correct adapter for your application. It would be a good idea to get the numbers from your head and block to verify that you have what you think that you have. When I bought a '66 Mustang, it came with a '78 200 block and a '77 250 head. The previous owner was completely bumfuzzled as to why he couldn't get it to run with an Autolite 1100 and no adapter for the large log head. The guys here helped me get on track to get it right.

Hello Don,
That is great information. I will take your advice, as it sounds like it worked out for you. I know with the stock ford head you can only squeeze so much hp out of the inline 200.
Thank you very much for the information and taking the time to help me out, I really appreciate it.
Jeff

Hello again, which Rochester carburater is a direct fit. I found a bunch on ebay like you said. I'm just not sure if there is a specific Rochester carburater. Will the Rochester work on my 200, which isn't a large log head?
Thank you
Jeff

The Rochester can be a direct mount with an adapter and opening up the carb hole on the log. I really did not word this well previously as I usually think in terms of milling the head as opposed to direct mounting to the existing carb mount. I am attaching a link with good information from some of the very capable forum members:

I am looking for the small base Rochester for my project. I think it will be easier to mount? 280 cfm so should be good for me, considering mileage also.
Rochester should attach to your non-large log head just not sure how much the small log could affect performance.
This Rochester mod is kind of a new thing from what I can see.
I have some other info that may be helpful I will send along.

Thank you for that info. I am down to the Rochester and the weber 32/36 with adapter plate. I will read the link you sent me.
Thanks again, you've been a great help

Yeah I have a lot of this stuff:

Although this post is old....I found this today & thought I'd post it:

From a company called L.L. FULTON Inc.- Great Falls, Montana
(I think they specialize in Rochesters)

FAQ Section --> "What Size carbs do you use?

We use the Small Base Rochester 2GC Carbs in ALL but a few of our applications.
- The Small Base Carb is IDd by the air cleaner flange diameter of 2 5/8.
- The Large Base Carb is IDd by the air cleaner flange diameter of 3 or 3 1/16.

http://www.hotrodcarbs.com/faq.php#sizecarb

The small ones have 1 7/16" throttle blades.
The flange bolts are centered on a 3 1/4" X 2 7/8" rectangle. I don't know about the bigger ones sizes. Smokey

t's all here in this link:

http://www.carburetion.com/quadnumber.htm

703 is from the '60s with A.I.R.

8 is 1968

5 means California emissions 2-barrel

1 means Chevrolet

9 odd number means it came in front of a manual transmission.

So it could have come off a 1968 Chevelle with a 307 that was sold in California, 3 on the tree.

I'll try to stop now.

If memory serves me correctly, the Rochester 2G has a relatively small base and, at 280 cfm, would be a great option. By virtue of its small base, meaning small-ish bolt pattern, I believe adapting it to your 200 would require relatively little less hogging out, which should make it easier that a more extensive, milling and brazing.

IMPORTANT INFO:
I thought I had sent this earlier but had not and it will be very helpful with pics for fitting the BBD to the existing carb mount and will likely apply to the Rochester and Weber if you go that route.

This could be a deciding factor as pointed out by Frank. It appeals to me because I would like to use my original factory air filter housing.

That's a definite bonus. Would you say the Rochester is a better choice over the 2v Weber 32/36? If so can you recomend where to purchase the the correct carburator and matching adapter.
Thank you I appreciate the help

No I could not say it is a better choice, just that using the stock air cleaner may be an advantage to you. Best to have all pertinent details. Since you can buy a new Weber, jetted for your application and with customer support that is a big advantage.

That is a big advantage. Clifford performance installs the custom jets and basically has the carburator tuned. Does that member Bill do the same thing? Would you recomend the 32/36 or the 34/36?

 

[Frank]

Does that member Bill do the same thing?

Yes sir. He is a decades-experienced distributor tuner, and tunes the curves specific to the engine application. He solved my detonation problems on a 300. 100% pro.
