Let's get this slant turbo project started. 71 Dart
The one on the left looks like a boat carb, you sure it's a 350? Usually those are about a 270 or something and they came on International stuff. The other carb looks like it would work just fine but appears to be missing a lot of pieces?
Also your supersix rusty looking intake with the single adapter plate is exactly how my carb is mounted. Did you go with a 6" radius for the U bend or longer?
You know I don't know for certain if it is a 350, it was sold to me by another member as a 350 but I know he used it on his turbo project with good results. The price was right and it was a known quantity so I jumped on it. He threw in the adapter which was great as now I don't have to find one. The rusty intake is a spare I picked up a decade ago when I was able to find Super 6 setups at Pick n Pulls. Have not seen one in ages. My dart came with a good running super six intake and carb on it. Had no idea it was on it when I bought it. Works much better than my 67 slant six super six did.
The other carb is a 6425 and I believe a circle track carb. 650 cfm. Here is link with some better pictures.

I got a good deal on it earlier in the year or last year and it was admittedly an impulse buy, but I wonder if I can make it work? Guess I can put it on and see if it works? Two of the other carbs were free and the other is one I got off FABO for 10 bucks. One is a 450 vacuum and the other is supposed to be a 600 vacuum, the big one is hard to identify as the choke horn has been cut off, but supposedly came off a 427 chevy. Too big and not a true double pumper. These are parts carbs for the most part.
Mulling over getting a 600 or 650 double pumper in the future if the big two barrel does not work out. The big two barrel is discontinued and not a lot of information about them. I found a couple posts about them not being so good on the street. The 650 double pumper is a very common carb, lots of different uses, lots of parts, it may be the winner in the long run.

Today was all about fighting my way into the garage and finding all the parts I have been accumulating. See what is missing and what I think I still need. Found a battery box and battery tray. I think I will go with your idea of bolting in the battery tray. Save the battery box for another project. Picked up 20 feet of welding cable recently, think I need a couple more terminals. Also thinking of putting on a kill switch for theft prevention.
