Matching Numbers???

Very helpful info from everyone. I'm new to the mopar thing - actually, to the cool older car thing (aside from my first car being a 65 Valiant back in 1986). If there really were only about 2,000 V-8 convertibles made in 64, is this car valuable? Also, I bought it after it had a lot of work done. It has a new intake manifold with a 4 barrell, but I still have the original intake and 2 barrell - should I keep the stock stuff? Any input/advice is appreciated!
