What are the /6 One bbl carb options

64 /6. What are the options for a single bbl. I don't want or need performance. I any just want to stick with factory 1bbl. I don't want an emissions carb either.

Is there a specific carb that is reliable? I'm thinking of finding/rebuilding one. If I buy one from the parts store, what car/truck do I ask for? Suggestions please.
