don't know if it is to big for your combo, but i do have a edelbrock 800 thunder series carb with maybe 200 miles on it,worked awesome on my set-up similiar to yours,decided to put a 6 pak on,otherwise a great carb., but the one thing i didn't like was it actually "looks" small on a 440, but i do also have the street/strip holley dominator intake if you are interested pm me, good luck Darren
