RE: What carb for 71 383 magnum?
Get a new or rebuilt Edelbrock from Summit Racing.
They are tuned better for Mopars and Summit has the best prices. (They should be paying me for my endorsements.)
You can screw around forever with the old carb and still have problems. Drop $200 or so on the new Eddy and you'll be happy.
Smaller is better if you don't have a cam.
