Several guys here in the North Texas Inliners chapter run dual Carter/Webers on their 235s. We get them from Tom Langdon at
Stovebolt Engine Co. Admittedly, we may be a bit biased because Tom is a longtime member of the Inliners organization, but people do seem to be very happy with the setup. One potential drawback is that there's no real tinkering to be done. You just install them and go. This will disappoint those who revel in rebuilding the old pieces. There is, of course, fabrication for fuel lines, manifold heat, and linkages. This might be a good option for your driver.
Here's a
link to a set of pix I found on the web (no one I know).
