What was the original factory carb installed on 1968 200 c.i., 3 speed C4 auto trans, convertible? Was it the Autolite 1100? I have a Holley DOPF-K 1940 replacement carb on mine that was there when I bought the car and it sucks. I rebuilt it and adjusted the linkage so I have full open throttle plate when the pedal is fully depressed but it still stalls under quick acceleration. I see Pony Carbs has an new & improved 1100 and if that's what origially came on the car I'd like to get it.

 

According to my 1967 mustang shop manual, the carbs were either the autolite 1100 1-v or the Carter YF Type 1-v. Heard good things about Pony Carbs but kinda pricey. Might try ebay for autolite 1100 if you want to keep original and try to rebuild the carb. Those 1100 are hard to adjust at times as I have that one on my 67 stang. Keep us posted on your progress....

I was in the same boat as you. I have a 68 coupe with the I6 200 and it also had a mickey mouse setup with a Holley 1940 carb and a homemade spacer plate. I pulled it off, bought the correct spacer plate off ebay for 20 bucks and installed a rebuilt Autolite 1100 carb. It improved performance X 100! I would definitely get the Autolite carb, and from what I have heard (second hand) the Ponycarb unit is better than the original. I would get firsthand info from someone who has purchased one before dropping that kind of coin on one though (around $500) Otherwise, find a used Autolite 1100 on ebay/swap meet/neighborhood mechanic for $100 and rebuild it yourself for $20. Use the Holley as a boat anchor or some other worthwhile paperweight type item.

Yea good question. Id like to replace my carb on a 67 200ci but I dont know if its the Autolite or the Carter that came with it. I was looking at that Pony Carburetors Autolite replica one... Anyone know whats the right carb for them?

 

What's the difference between the two? One easier to keep adjusted? Can a 2-V be installed where the Holley now sits? Does a 2-V give better performance, quicker pickup, etc.?? Thanks.

 

How do you know if you need a spacer plate?

 

To answer both questions.... I have never seen a Carter carb on an I6 Mustang.....not that I have extensive experience with them and I am sure someone will refute what I am saying, but I have only seen Autolite 1100's on them. Second, my understanding is that the factory intake system on these engines was less than optimum. They just didn't breathe well. Clifford has many upgrade options to increase performance of the I6, but can cost you more than just your lunch money. Dual out headers,, X pipes, intake port splitters etc, are all available.
Good Luck!

OK. Pony Carbs has an autolite 1100 for $219 - 1100 venturi upgrade (whatever that is) for 1968 is $35 extra. Concours carb runs about $70 more. Anybody using the "new and improved" 1100 from Pony Carbs?

 

Regarding the spacer plate.... you will definitely need one. If you try to bolt the carb directly to the intake manifold studs, it would hit the valve cover. The spacer plate has holes to mount to the studs, then two studs that are rotated about 35-40 degrees so the carb sits correctly. NPD and MU sells them new for about $40

I'm using the Pony Carb and it has greatly improved performance. I highly suggest it.
