2 bbl to /6

I too am trying this conversion. Have yet to find a pic of a converted
throttle linkage (going from perpendicular to parallel to engine) I have a
2bbl manifold w/ Carter bbd but don't know if its right (1 1/4 vs 1 1/2) ?
would 1 1/2 mean more cfm and what is too much? Carb came from
a dodge d100 truck, don't see a dash pot, or bowl vent. Should I
can this one and start looking around?
