OK with TQ guide in hand here's what i have found that I think would work:
-6139S is for a '72 340 automatic (needs a rebuild). -6324 is for a 73 HP 440 automatic (newly rebuilt) -6090 for a 72 400 auto (newly rebuilt) **4968 Carter AVS for a 71 HP440 auto (newly rebuilt)
will any of these other carbs work well on my 340 ? Will a carb for a 440 HP be too much?
The 440 and 400 carb will be the same, maybe with a little different jetting stock. The link should say which jets are in there. But any of them will work with some time spent tuning.

You don't need to worry about over carbing with the 850's.
Hotroddave40 got 29.5mpg in his super mileage 318 Cuda with an 850.
Get the "biggie sized" TQ to start with! The TQ will only pull what the engine demands from it.
What I would like to see is how to mod the emission carbs. How to mod the spray bars etc.
I really want to bolt a 318 model TQ on a hot slant6.

Yeah I'm familiar with the air door but that only regulates the secondaries and there is lots of throttle movement between idle and when the secondaries crack. Till then the air door does nothing.
Perhaps the 1.5" primaries are still small for a stock smallblock, I'm just sayin'.
