freak,
Just one is fine, all you need is a vacuum signal of some sort for the distributor.

Make sure you adjust the carbs to have the same vaccum at idle. They must be balanced.

You'll also need an extra fuel line (to the nearest gas pump)

, and if it's on a car you intend to drive every day, you'll be VERY disappointed in its driveability and throttle response, although it'll be terrific at WOT over 3500rpm.
