Can a carburetor be too big for an engine?

According to all of the carb charts you are too big for a street engine. The race 289 used a 715 cfm Holley. You would need a lot of rpms to really need a 750. Throttle response and smoothness of acceleration are some of the problems with too big a carb.

Can a carburetor be too small?

If the carburetor is too small, it restricts airflow into the engine. The cylinder can't fill up all the way. This starves the engine and results in slow acceleration and a lack of top-end power. A larger displacement engine running at higher rpm will require more air and fuel.

Can you have too much carburetor?

The carburetor feeds the engine exactly what it needs: fuel and air. Give it too much air and fuel and it'll get lazy and sluggish (think Thanksgiving), give it too little and it'll starve (think the movie Castaway).”
