Ah, the beauty of carburetors... No doubt one reason I prefer fuel injection.

The IDTs are three barrels, if I recall. There is also an IDA 3C, which  is 
another flavor of three barrel.

You had best re-check your sources.  Late time I looked at the  Weber 40 IDAs
on my Corvair they were three barrels  each.


Okay - Weber makes (made) a series of carbs called the IDA. There are  36IDA, 
40IDA 48IDA, evan a 58IDA and robably othes. Those were 2-barrel  downdraft 
carbs.  Weber also designed a  pair of Three  barrel versions for some Alfa 
Romeo V6 in the late 50's. Many parts are  similar to the 2-barrel versions. 
They 
were called the 40 IDA3C and  40IDA3C1 (Left and right - the throttle linkage 
differs). Porsche adapted them  to the new 911 motor in about 1963 or so. 
They also used Solex 3-barrels and  Zenith 3-barrels over the years. Like 
most 
manufacturers, Porsche made some  changes on the carbs, reflected in other 
model 
names like 40IDT3C  and 40IDS3C. The pre-Fuel Injection Racing Porsche flat 
six cylinders  used larger three barrels - Those were 46IDA3C and 3C1. 
Several 
racers have used  those in non-SCCA  competition on Corvair/Stingers. 
Wink-Wink,  Nudge-Nudge!
