Probably the easiest set up is the new Eddy AVS Thunder series carbs on the stock AFB intake with stock carb spacing making for the easiest way to add the shaker
if you use the holleys a Pair of the 750 Avenger series vacuum series or the 750 HP 82751 carbs will be the best bet
is this stock CI , Which cam choice , what si the application , crusing , street strip , ETc , what gear etc ?
