It's a Autozone brand carb that I bought for my old 77 350.

You would probably have better performance with the Q-jet and without the adapter, but that's just my opinion. 

If the Q-jet sucks, swap carbs and use the adapter.

Just learn how to tune it (grin).  Lots of stuff online, and excellent books on the Q-jet (Cliff Ruggles book is good).  A properly setup Q-Jet is an awesome thing, but few people want to learn them well enough to set them up properly.

Autoline is a rebuilder, could still be  a Qjet.

^this.       Lots of variables, depending on when.
History of carb, did it run good before.
Off idle stumble, cruise stumble, ?

Any off the shelf carb you buy for ANY vehicle is NEVER a bolt on and go setup. You will need to tweak and tune that carb to run right.

1406 needs a fuel regulator or you'll flood it.

Hard to say what the rebuilder did to it. They try to make them generic so they will fit more applications.
Stumble off idle could be lean or rich. Improper pump shot, over rich or lean idle circuit. If you can disconnect the acc pump linkage and blip the throttle in neutral/park and see if the stumble gets better or worse. Watch the linkage doesn't get hung up tho.,
