I an almost guarantee that the 2 barrel will be too small for that engine...once you establish what size carb you need for that set up, then you can buy a Quadra jet but as Aus78Formula mentioned, your car will be worth a lot more, and likely run better with a carb that matched the year of your car. If your not concerned with that then find out what CFM carb you need for your set up and order the right one.
Be patient and keep doing some research on it and you will be much happier in the long run.
Often you tend to spend more money over time trying to swap parts to get that right combination of thing when a little bit of digging and patience would have been all you needed
Listen to what everyone has to tell you, read all you can, learn all you can and decide in the end what works best for you and what is along the ideas you want to do
