If you have the vacuum operated doors for your climate system, it will need a manifold source as well. Usual place is the manifold port behind the carb.
If you are planning on using a OEM type cleaner cover, it might interfere with the fuel inlet. Mine did. Fix was switching to a banjo fuel inlet.

In terms of advance, the vacuum advance port was already capped off at the distributor. Stock GM distributor. Is that also wrong?
