Now that Holley has discontinued the #4224 660 center squirter carb, I decided to do a little R&D to develop an upgraded alternative. As a result, I'm now able to build a double pumper carb that is the same length or shorter than the 660 center squirter, with at least the same airflow capacity. For guys who want to run an inline dual quad setup where the carb center to center distance is 7.875" to 9", this allows us to now use double pumper carbs, which allows for a much wider choice of linkage action on each carb,compared to what the 660 center squirter design allowed.
This makes these carbs useful for a wide range of applications. So, for tunnel rams, blowers, and other dual quad setups, like the dual quad tunnel wedge intake for the FE Fords, this approach gives the opportunity to upgrade inline style carburetion for both drivability and power. These carbs can flow from 700 to nearly 1000 cfm each, depending on venturi and throttle bore sizes, and the type of venturi boosters used.
