You've made a couple of posts here on the same subject and I'm kind of trying to answer both on one post. Anyway I have never seen a 6 X 2 intake for a small block Chevy.....however if you do come across one I think it would be the one you would have the most success with making streetable.

Ok you’re probably asking why a 6 carb intake would work better than a 4 carb one if the 4 carb one is too much carburation. It all pretty much boils down to the basic design of the intake. On the 4 carb intake by its design it requires that all 4 carburetors work at the same time (have synchronized linkage) On the 6 X 2 intake the carbs can be set up to open progressively and the timing and amount of opening end 4 carbs can controlled by the linkage. Basically you would only be running on 2 carbs the majority of the time and the end carbs would not open until the engine is an RPM range where it can actually use the extra carburetion.

So far it’s only running on the test stand, but all indications are that it will work very well once it gets in the project it’s intended for.

The picture if from when I was setting up the linkage.

Here are a couple of videos of the engine…..the first kind of explains the linkage and the second shows it running.
