I have a 1957 E Model Tbird does not have the original teapots.
Will it run fine with carburetors ECZ9510-1161A & ECZ9510-1162A

Thanks Mike

This is a tough question. To me much depends on your transmission. Automatics don't handle the extra carburation in my opinion. As to your question, the carbs you have specified are two different types of carburetors, even though they function somewhat the same way. I would seek out another 1162A if you are bent on doing the 2x4 change. As the original carb linkage runs both carbs at the same time, using different functioning carbs will cause nightmares in timing the carbs. Also, be careful who does the rebuilding as they are called "firepots" for a reason. Also, your non-original teapots are not ventura reduced. Your 1161A and 1162A types are about 400 cfm each while the originals are about 370 cfm each. If you are wanting safe dependable transportation you might consider using a Holley 650 double pumper with electric choke. That will upgrade the vehicle performance considerably. Hope this helps in gathering information to make the right decision.

Hi, I have two 4-barrel tea pots on my 1957 Thunderbird. ECZ 9510 1162-A & ECZ 9510 1191-A

Will the car run correctly with these carburetors?

Thanks Lee

A source you’ll want to consider is the 2x4 intake dyno comparison that Ted Eaton published in Yblock magazine a few years ago; that article (“2x4 intake manifold testing on iron heads”) is also available on eatonbalancing dot c o m. His dyno runs tested a variety of carburetors as well as a range of different intakes.

I once looked into doing this but never got around to the actual installation. But if memory serves, you’ll at least need to change the jetting and deal with the vacuum secondaries. And, if you’re detail-oriented, you can also compare the component parts lists for the different carb versions as they were published within the 49-59 Ford Parts catalog. Pls let us know how this works out and what you ended up doing to get there.
 
It sounds like you need to start with basic diagnostics first. Do you have good spark? Timing issues can make for hard starting, are you actually getting a good fuel supply?

A bad ballast resistor can be the cause of that. Put a jumper across the ballast resistor and see if the problem goes away. To be safe, and if it does run, don't run it that way for more than several minutes if it runs or you may overheat the coil.
