Carb size - general rule of thumb is CID x max RPMS / 3456. You need at least that much carb. A little larger if you're using a dual plane intake.
Intake type - if know you'll be using a squarebore carb, get a squarebore intake. If you'll be using a spreadbore carb, or might be, get a spreadbore intake.
Obviously, the information you provided isn't enough to get more specific. What you'll be doing for cam & heads is also important, as is what you plan on doing with the car when you put that engine in it.
