David Vizard bench flows a BBD 2bbl

Always wondered what these carbs flowed just out of curiosity so enjoyed the video.

Most surprised at DV failing to mention an important, & limiting, aspect of raising the rocker for supposedly increasing the ratio. The rocker ratio is generated in two parts, the prod side & the valve side. Raising the rocker to use a longer prod might be detrimental to the overall ratio because it changes the geometry detrimentally on the prod side.
