Identify this intake system?

Those are two barrel weber carbs. They are fussy and require almost constant tuning but haul *** when they are right. That is an Aussy Hemi 6. I have not seen a /6 with that set up but I am sure somebody has done it.

Thank you!,
Do you think it would work with a slant six, And do you know what type of intake manifolds those are?

The video on youtube states that it is a slant six...
