340 carburetor selection advice

Thank you all for the replies!! Right now I’m leaning towards the 750 Holley 3310. I have more experience with holley’s and I can pick one up pretty reasonable. The thermoquad I did some research on I have checked out prices and everything Bewy said is on point. Olmanmopar and rumblefish advice on the Holley/ quick fuel looks good too. I took a quick look online at pricing I will check look into them all in detail. Also the cam choice seemed a little off to me too. At this point my priority is to get the electrical strait. Put the intake and carb on it and fire it up see how it runs. If I eventually do some upgrades I want to be in the ball park with the carb.
As a side note, the guy I bought it off of really didn’t know much about the car. I was lucky and I called a phone number written on the back of the title and it was the original owners son. That is where I got most of the info on the car. So again thank you for taking the time to respond to my post.
