1963 421 Super Duty dual quad setup

This was just completed for someone in Pennsylvania. It will be going on a 421 cubic inch engine and is calibrated with .092 primary and .070 secondary jets, and .051x.061 metering rods. The carburetors were cloned off of 3012 348 Chevys. One picture shows the carbs being flow tested on my 389 test stand engine.
