Well, Holley may have made a smaller one for a manufacturer but the smallest
they sell aftermarket is the 390 - a 4161. The next step up I believe is
500cfm which is available in 2bbl and 4bbl sizes.
With the vacuum secondaries on the 390 you should be able, theoretically,
run the carb on a 2L as the secondaries will only open as much as the amount
of vacuum created by the engine.
The primaries probably flow less than Solexes.
