Does it have 5 more circuits than a regular QJet, like that Edelbrock thing?
Some parts exist for no real reason other than because there are people out there with too much money who will buy them.

Working on one now , so I will let you know how it turns out. I do know they are made in China . The casting and machining looks very good but Its' the details that matter. So far I have it all apart to measure every thing. Already I can say there are some details to be rectified. I have been pretty busy so it may take a few days.

Are thy still a Zinc casting? Wonder why the flow rating is so much less? Thanks for taking the time to look at it.

Change in air flow could be because of change in fully open position of air valve &/or sec t/blades.

Aluminum casting . I,m already getting frustrated by the repairs needed to even test this carburetor, and I am not talking about jetting/air bleeds.

All it's missing is Bluetooth so you can adjust it with your damn phone.
