Default What's an IHC Teapot carburetor?

Hi,
According to The Carburetor Doctor "... Governed models were used on IHC trucks into the early 1970's..." I never heard of these "teapot" carburetors before.

It appears a lot of effort was put into their design and they surely must have been much more expensive to manufacture, but why? What can anyone tell me about them? Can they be tuned like a regular carb? Are they more powerful, smoother or more economical to run?
What was supposed to be their benefit or how were they supposed to be better than a regular carburetor? Were they better, the ultimate carb, or just an over-engineered towering pile of junk? Do they have any advantages over a standard carb?

I never saw such a carb before in my life. Thought I'd include a couple pictures of one in case there are others who have never seen one before.
If anyone knows anything about them, please share. Let me know what's up with them, and if known, which models of trucks they were optioned for etc. Just really curious.

Thanks.
Steve

My understanding on the reasoning behind the "Teapot" design is, that in order to incorporate the throttle governing system, and the barrels while meeting the foot print envelope (top of intake manifold bolt patterns), they needed to move the fuel bowl and what not up and away from the throttle body.

In short, the design came out of necessity to fit existing intake manifolds.

That is not an IHC carb, but a Holley carb.

wow, you sure did some homework there.
That's about everything I could ever want to know about that carb.
Thank you.

The "Teapot" was not just used on the 50's ford passenger cars.
The teapot was under many list numbers and predominantly the 2140-G (G = Governed). Found 15+ specific IHC applications mainly V549 and a few 450's.
http://www.tocmp.com/manuals/Carbs/Holley/MasterList/
A few GM's too. The one pictures in the OP post was list 1960-2 2140-G app GM 283, Military truck.

While these 2140's are 4 barrels there are 2 barrel versions also.

A similar 2B carb was on a B160 dump truck I had. It was on a 264 engine and there was never a bit of problems with it, even with all the rusty gas it was fed.

I can one obvious advantage to moving the fuel bowl up off the intake, it should keep it a bit cooler.
