Dual quad info

I would think that to run 1:1,
your engine would need to run a good amount of idle and low-rpm vacuum, which is gonna depend an awful lot on either,
a) your Cylinder pressure/total chamber volume/and intake closing angle, and
b) the stall/and gears, or
c) some combination of those, and, not to ignore,
d) the size and type of the chosen carbs

At my age (69) I wouldn't be excited to run them on a low pressure/low vacuum combo, in 1:1 .
