You need to talk to Danny Ashley, and/or Dean Oliver, among others, both are members here. I'd be looking for a 69-75 4MV genuine Rochester QuadraJet, with a "704" number on the side, such as a 7040203, or a 7045213. Those numbers are just examples. The "704" means it is a 4MV divorced choke style carburetor, the next digit is the year of manufacture, and the last three are the "model". You may need to find several cores in order to get a good one. And you'll find that what looks good on the dyno may or may not run good at the track.
