I don't have the info your looking for on that Edelbrock carb, but my suggestion would be to put a Victor Jr on there and a 750 double pumper or 650 holley. These carbs properly converted are much easier to tune for the blow through stuff and the single plane intake will make fuel distribution better underboost. We've got a Twin turbo Banks Sidewinder 350 that makes a minimum of 700hp on pump gas with out an intercooler setup.
