Here's a writeup on the car.
He doesn't really get into the carburetion other than to mention that they did it to be different.

In reply to Trans_Maro:
Hmm... I guess if all the carbs are jetted correctly it wouldn't matter.
My guess is the upper carbs are set up to act like secondaries and only start flowing fuel when the air flow/speed is sufficient enough to keep the atomized fuel in suspension as it passes through the lower carb.

OK, Andy. I don't get it. Explain what is happening
but it’s the one-of-a-kind intake setup that puts this motor over the top…literally. Peeking above the coupe’s hood line (if it had a hood) is a pair of polished intake scoops, feeding dual 2GC Rochesters, plumbed to—wait for it—another carburetor; this time a 750 cfm Edelbrock Performer. “I wanted to do something unique, and I think we found it,” Mike said, who credits fellow hot rodder Dave Lynn for dreaming up and constructing the coupe’s incredible intake. “We’ve still got a little bit of tinkering to do before it’s perfect, but Dave’s wheels are always turning,” he says.
Sounds like it run like we expected
Wouldn't throttles on the upper carbs act like chokes to the lower? The only way I can see it working is with the idle and mid-range fuel circuits on those Rochesters plugged and their throttle plates being wide open or shut for choke. Jet then and the single carb both lean so the fuel they each add to the same air adds up to the right amount.
No value added for the extra hardware.
Or they've got fuel lines and linkage with plugs in the float bowls.
Just run the two rochesters on top as butterflys like a shotgun scoop has.
Either way, it's a whole lot of work for something that probably runs worse than a single, properly sized carburetor.
reminds me of this useless and mostly non functional blast from the past:
or this blast from the not too recent past:
i actually saw the 8 tubocharged 57 Chevy in person at the Car Craft show... everyone was laughing at it..
Yeah, its awful because doing something different is the Devil.

different isn't always good. if running 2 smaller carbs upstream of a single bigger carb was the way to make MOAR POWER, then people would already be doing it..
It's a show car... it doesn't have to run well or make more power... it just needs to stand out. Different mindset than the GRM world... but not necessarily bad.
I'd be laughing at that octo-turbo car too... but I'm sure that's what the builder intended. Either way, one can appreciate the fabrication and finish work.

i saw that octo-turbo 57 Chevy in 2008... it was parked under the canopy at the GM trailer at the Car Craft Summer Nats... people were giving it a passing glance and shaking their heads as they walked right by it to look at the "Bumblebee" Camaro hero car from the first Transformers movie, the one that was built on a GTO chassis. there was also a preproduction '09 Camaro there that had a huge crowd around it. yes, it was different, and no, no one cared...
