Rochesters from a pontiac,chevy 348, caddy or olds wont. The corvette tripower carbs certainly will . The vette carbs and the 340/440 carbs are all variations of 2300 holley.
I agree. I ran my 6 pac Holleys for 12 years trouble free before the car went to Australia. No complaints from the Aussie either. I never ran any ethanol through them and neither did the Aussie. I think he told me their gas was something like 110 octane and they don't have any ethanol fuels. Seems to me, the Holley set up is as good as it gets once they are set up properly and you don't feed em any corn. Not that I endorse Holley. When it comes to carburetors, I'm a Carter guy Especially the Thermo Quad.
The 2300 above came from the factory with them.
The discussion here is 2 bbls, but from my experience the Rochester and Carter 4bbl Quadrajets performed quite well. My 440 loved a Quadrajet with an adapter plate, I just wanted to see how it would run and was quite impressed. Chrysler used Quadrajets after the Thermoquad went out of production, before moving on to fuel injection systems.

I dont know much about the six shooter setup, probably because i thought of it as a very expensive, small cfm setup for a small block chevy. I would guess the carbs would be similar to 2300 holleys. i dont know of any reason they couldn't be made to work. They might be a little small on a 440, or they might work great? I have seen tests of that setup on a 350 chevy but frankly, i dont remember any huge performance benefit, but i do remember a huge "suggested retail price". They struck me as almost three grand of eyewash for the ratrod crowd.
