73 Fury 400 Engine – help needed in choosing a new carb

Hi guys,


I want to change my 2bbl carb for a new 4bbl Holley carb in my 73 Fury 400 engine.


I preger low end power and torque and i know the engine is a low-compression.


I don't want the carb to be too big so i was recommended on the 570cfm.


The final options are as follows:
