A half truth is a whole lie.
Pot, meet kettle
While much of what you say about the TQ is true there is a lot of what you say about the "Carterbrocks" that isn't.
http://www.edelbrock.com/automotive/mc/carburetors/avs2.shtml"The AVS2 Series is the next generation in Edelbrock carburetors. The AVS2 features annular flow primary boosters with a new calibration for improved off idle and cruising performance."
Seems your info is 50 years out of date.
So, Edelbrock has finally brought 2 carbs to market with a single improvement to their otherwise outdated design. A 500 and a 650 with annular boosters. Hardly qualifies as 'much of what I said about them was not true'.
And, does that mean the addition of annular boosters on those models is enough of an improvement to obsolete the other current CarterBrocks for most street applications like the OP's?
Annular boosters are often a good thing for street applications. But that still doesn't put these little Edelbrocks on the same level as some of their competitors.
Besides, wouldn't most here recommend a 750 for the OPs application? If so, then the OP would have to settle for a non-annular design of CarterBrock. And I hope that the OP's application still matters to this discussion.
For the umpteenth time, it's not that the CarterBrock design is bad, it's just that there are better designed carburetors out there right now.
