They already got them set up on their site but not selling them yet https://www.edelbrock.com/catalogsearch ... carburetor

Thoughts on their design???

I suggest you pass. There is plenty you can do with standard Holley style carbs, and all that emulsion and intermediate is just not needed.

Who do they have design these things?
As Mark said, many of hte features seem like an answer in search of a problem.
Alos I do not believe they have shipped any yet. Must still be on that boat from China.
