Hello Frank, I would not use a double pumper on the street unless I were using a 3000+ stall converter. Those monsters are double rich to begin with and you really need some revs to kick them into the system. Use a vacuum secondaries carb if you're just street drivin' with it. A 780 would work great. By the way, good job on matching the cam intake duration to the static compression ratio. Should be fun and run detonation-free on pump gas.
