Which holley for 340 magnum???

Hello,
I've been pawing through the threads hoping I would find a silver bullet thread but I didn't although there's a ton of good info there. I am going with a Holley for my Duster, I have a high compression 340, Edelbrock RPM Air Gap (on the way), 904 trans (TQ to be determined), 8.25 rear end 3.55 ratio, cam tbd. I will have headers, not sure what will work with Magnum EQ heads (LA intake pattern). I plan on mostly street driving but I don't want to run out of power if I wind it up. I want to know if a Holley model 750 would be a good match. I need a choke (Northwest), prefer an electric and vacuum secondaries. I would appreciate opinions suggestions about Holley choices, if it's the right size for what I'm planning to do, model numbers?

Thanks!!!
