Does anyone know the size of the factory 4bbl Rochester Carburetor (cfm) that came on the 350 H.O. and the 400 cubic inch for 1969. Reason I'm asking is because I'm building up my factory 69 350 2bbl to 350 H.O. specs with the 48 heads, .67 cam, 4bbl intake...etc but have no idea how big the 4bbl carbs are that were used for that year so I can properly match with a Holly or carter carb.....dont want to have to much carb but dont want to have to small of a carb on there as well.
Manifold you are purchasing is a spreadbore, you may wish to consider purchasing a Quadrajet and having it calibrated to 350 HO specs by Cliff Ruggles. Banshee provided his contact info.
With the vacuum secondaries on the Quadrajet, the carb "size" is controlled by engine demand, up to 750 cfm with the body used on 68s and 69s.
