69 Chrysler 300 carb

My recent purchase 69 Chrysler 300 has a bunch of things that need "unfixed". I haven't fooled with this yet, but it looks like the choke is wide open when engine off/cold. Are the secondaries mechanical or vacuum? They don't open at all when looking down the throat.

Is the 1406 carb (the number on the base is 1406 1284), good, bad, ugly? ( I peronally hate the chrome.) Engine is a 350hp/440 that will be pulled and upgraded a bit. Is this elderbrock a good starting point for a carb or...
