Which Carb Type?

Carter, Edelbrock, Holley or Demon- they will all work if properly set up. Go with what you are comfortable with, or with what your friends are comfortable with, that way you will have some help and maybe easy access to spare and tuning parts.
BTW- if you are going to buy parts based on their resale value, might as well not bother as they are never worth as much as you paid!
