If I go with a "B" manifold on my 292 and get rid of the teapot I would like to get a carburetor with heat activated automatic choke like the original teapot had. Would this Holly 4160 (designed for early Mustang) be a good choice? http://www.ebay.com/itm/321044154666?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Thanks, Alan

For reasons unknown, the "link" I included above for the carb on Ebay does not work. The Ebay item # is 321044154666. And by the way, I am not necessarily looking for maximum horsepower, just good reliable street driving performance. Thanks, Alan

When pasting copied links into a post, simply add an extra space after the link to activate it. I edited your post so the extra space is there. As far as carb choices go, here’s the summary of the dyno test I did with a variety of carbs on the 312 dyno mule. http://www.eatonbalancing.com/blog/2012/09/25/four-barrel-carburetor-testing-on-the-y/ . The Holley list #1848 is the recommended replacement carb for the 1957 Thunderbirds and works well as a bolt on replacement on most stock headed Y engine combinations.

Just my 2 cents worth.I would be looking at a brand new replacement carb.Rebuilt or not they are still 40-50 years old and who knows what "mods" have been done to them by a carburetor "expert".There are 2 new ones on Ebay that might interest you.The 465 cfm hot air type choke like you have now or the 390 cfm electric choke which is what I have.Item #'s 390509529641 and 330839981062.These are available from different sources and you might find a better price.

Thanks all for your help. I went ahead and bought this new Holley 1848-1 Carburetor on Ebay. http://www.ebay.com/itm/160934169847?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Thats a good choice.You will be much happier with that than a rebuilt for not a lot more money.You might want to consider adding a 1/2 inch phenolic spacer under the carb.Keeps it cooler as it creates a non heat conducting separation from the intake.Also you might consider blocking the heat crossover passage in the intake when you install it.Same reason-helps cut down heat to the carb.You are aware you will need the 57-up distributor to go with that carb?

Couldn't tell for sure from the eBay page/photo: Does that come with an included electric choke at that price?

That model is hot air choke only.Very similar to the original 1957 carb.

Will do on the phenolic spacer an the blockoff plates for the heat riser. Yes, this carb will work out fine as my engine is a 1961 292 fitted with the original distributor. Question...does this carb use both the choke stove tubes, i.e. the inlet and outlet just like the original or does it have one one fitting at the base of the choke? I see only one choke heat tube fitting in the pictures of it. Thanks, Alan

It would be one inlet fitting only.There is a kit you can buy on Ebay that fits the stove into the exhaust manifold and run one pipe up to the choke.Not common knowledge but Ford provided a "service repair kit" even back in 56 that did away with the original choke pipe setup through the intake manifold and put the choke stove in the exhaust manifold with one pipe up to the choke.If you block off the heat crossover in the intake be sure to remove the heatriser valve in the exhaust manifold if you still have it.If you look at Ebay item # 150966749827 thats a kit to replace the choke tubes you have now.Drill a hoole in the exhaust manifold and the fitting is sealed inside and self taps into the manifold.Bend the pipe and use the fabric cover supplied and you are all set.I have seen them specifically for Ford but that kit will work just as well.

Outside of what others might say about Edelbrock (and of course with good reason about how Vic Jr has been public about his disregard of the Y block), the last B intake I put together on a 292 (bored to 301) Y block, I tried a 500cfm Edelbrock with the manual choke. Out of the box almost 0 tuning was needed and it has performed well for the street. I personally like a manual choke and rarely is it needed for most that live in a milder climate/drive our cars only in decent weather. I recently got a hold of a 390cfm Holley 4 barrel from "Cactus" here on this forum in a little parts swap we did together and I will be installing that on a 272 pretty soon. I've only heard good things as well. The difference would probably be that Edelbrock carbs tend to be a little bit cheaper when purchased new, and the Holley carbs are a bit more. However, I believe that the Holley's are more common and there is more ability to "tune"... somebody else can chime in now, lol. Some of us on the forum stick to our carbs like we stick to oil recommendations. It can start a heated debate!

Curious: Does the add-on or OEM choke (repair) kit conduct actual exhaust gasses to the choke spring, or merely heat the air in the tube?
While I would be loath to add to my electrical load (6V Gen/OD) with an electric choke, if actual exhaust ever gets to the choke spring, it likely wouldn't last long.

I ordered one of the kits and I will let you know when I receive it. I wondered the same thing myself. Alan

The piece that screws into the exhaust manifold is a sealed pocket.All it does is heat up and the hot air travels through the tube to heat the choke coil.Ford used a similar system as a factory setup through most of the 1960's early 70's.
