If you're using the factory progressive style throttle linkage - you should - a pair of 750s will drive as if you have a single 750 double pumper. Ford used a pair of 600+ cfm carbs on stone stock 428s in the 60's - you are 50 cubes bigger.

At LEAST 600s and I would personally opt for 750s. I have a ton of these running on the street with good manners.
