Some neat stuff!! 1OL REDNECK
These look suspiciously like knockoffs of North American parts, no? Especially the 2 2-barrel to 4 barrel intake adapter. I'm sure it's not a new idea, but I've seen it somewhere before...

Looks like the casting even has bosses for balance tubes.
Neat idea, I wonder how it would run?
A strong signal to carbs but maybe not good for high rpms?

I think these guys built most of this stuff for Mercruiser (Chevy) Motors and Boat Racing. I found a page with a bunch of old speed boats on it. This would make sense, lots of water in Brazil.
PLus with the still now popular GM/Chevy style Inline 6 there, these parts would have a market.
However whether they are knock offs or originals, who can tell?
A strong signal to carbs
True - any semi-IR manifold (1 carb for 1 siamese port) does that, any balance tube or other connected volume reduces the signal.
not good for high rpms
Also true - horrible 90° turn right below the base. They were dealing with a height/hood clearance problem; a longer and taller manifold would have a much bigger radius, like 2" or more.
Not good for high rpms???? I beg the differ on that. My 3x4 tunnel ram intake see's 8000 rpms.Or is this just TBI or injection related?
Your design is far more developed than the one pictured.
