Brian, do you know if Ford rated their 2 barrel carbs on a different vacuum spec than the 4 barrels, like Holley did? Considering a 1.08" Autolite 4100 is rated at 480 cfm, I believe, I`m just kinda sceptical that even the biggest 2 barrel (likely from a 69-72 429 2 barrel), would be that close in size.
