Carb suggestion for a 512 with trickflow 270's

I'm building a 512 ci duster with 270 trickflow heads, I'm running an indy dual plane intake, it has 11/1 compression, it's mostly going to be a street car but will occasionally see the track. I was originally thinking a 950 double pumper would be perfect but after my dad was having problems with his 850 double pumper on his 440 with 240 trickflow heads and was thinking of going to a 950 himself I began wondering if a 1050 double pumper would be better for what I'm running. This is my first engine build so any suggestions would be appreciated, thanks
