I'm a racer, and I drive my car on the street. For me, its Holley hands down because they make the good power, and they are consistent at the track....so I guess you can add me to the "Holley=Performance" group, with the caveat of ONLY IF it is tuned properly.
Wow...that's a pretty open-ended statement!
An Elephant-Quad like that wouldn't run worth a damn on any kind of street machine, much less a small-block.
What are you running it on, and what would you run on a normal street-strip or bracket racer?
This quote tells me that you don't race, which also explains why you don't understand how someone could use a carb like that on a "street car". I have seen many small blocks with 1050's on them...heck, my small block could easily handle a 1050 dom and would more than likely go faster than my current carb that I built.
So I ask you, why do you think they won't run worth a hoot on a street car, much less a small block ((HINT HINT....its is the same reasons you have been preaching about the TQ))...............That's right, you don't know how to tune it.
