I currently have a Weber 32/26 and just received a new Weber 38 with new LCE intake and headers. Has anyone ever ran dual weber carbs on a 22R? Is there an intake manifold that supports dual carbs, and could you run a Weber 38 and a Weber 32/26 at the same time?

I know the 22R is not a powerful engine so there is likely no benefit, but I am curious since I am also upgrading all the exhaust components, and will have a perfectly fine 32/26 laying around.

 

No, they do not make a manifold for dual webers other than the dual weber sidedrafts. I have a feeling it would take some serious fab work to fab an intake manifold to do it. Even if you did, you would have 2 different carbs on each pair of cylinders which i could imagine would run real rough if at all. Not only that but good luck getting the throttle and fuel adjusted perfectly between the two considering the 32/36 has a lower cfm. So simply put, no, it is not possible.
