A 2300 Hlley 2-bbl 350 or 500, or 2100 Autolite /2150 Motorcraft or Rochester 2CG series rates 60% more flow.
Sucess is based on finding a matching set that are not suffering throttle shaft wear. They are kinda tall, BUT YOU FIND 'EM EVERYWHERE!
Brand new repro, they are $460 each.
It used to be a social function swap meeting these carbs. The 94s and 97s look like the old 1941-1953 Holley 847 7RT/7HA/7HT/8HA/8RT or 1956-1965 190x Holleys, but sure are two barrel.
The carbs are rated from 155 to about 310 cfm at 3"Hg depending on venturi size and listing.
Two of them can flow from 239 to 438 cfm when rated as a 4-bbl at 1.5" Hg (inches of mercury), enough for 150 to 275 horspower. The
The 1938 to 1957 era Ford V8 carbs were rebranded and listed
94 is the bore size = 15/16" or 0.9375", but the throttles are in decimilised form
1,
1-1/16,
1-5/32.
There is no 1-1/2" 94 specifically, but Holley made them in two 2110 series Bug Spray kits in two sizes, the 200 and 300 cfm items.
They were reporductions so you didn't have to raid every flat head 136, 221 or 239 or y block 239, 256 or 272.

Two carbs are then rated as a 4-bbl at 1.5' Hg for comparion purposes. So the smallest venturi items are together are 165+165, then divided by by the square root of 2. (330 cfm /1.414= 233 cfm).
