Looking through my 1969 Ford Muscle Parts catalog they list the 9510 AC/AD carbs as 652 CFM with a 1 5/16 and 1 3/8 sized venturi and 1 11/16 throttle bores. Also the 9510AH as 715 CFM using the same sized venturi and 1 11/16 throttle bores.
Is it the different type boosters altering the flow rate with all else being the same?
And as a side note Holley listed the 650 CFM 4150 series carbs as using smaller 1 1/4 and 1 5/16 sized venturi using same large 1 11/16 throttle bores.
So would the typical Holley 650 carb give same performance as the 9510 AC/AD 652 carbs?
And where does the 715 CFM 9510 AH fit in the mix?
