The burning question would be "WHY"? In order to take advantage of the extra airflow available from a bigger carburetor it's necessary to do a lot of expensive modifications to the rest of the intake/head/exhaust train. Putting one huge link into a flimsy chain doesn't improve the strength of the chain at all. You'll need to do a lot of modification to the ports in the head, install bigger valves, change the camshaft, and install a low-restriction exhaust system. In the process, you'll be building an engine that only runs well in RPM ranges that will bankrupt you in traffic court.
