carb question

Just buying 70 dart swinger slant six, needs carb rebuild or new 1bbl card. Where do you get parts for such a beast. Want to keep it stock for the moment so can drive it , then later will look to fire it up so to speak. Need to do research first on hypo options for this car. Would look to keep it slant six as opposed to dropping in v8, like to be different and already go the v8 in my cuda
