53Therapy - look for a Zenith from a G.M.C. 270 CID. Same size externally as the 9046, but smaller internally.

The internal size is ALWAYS more important than the external size (one can always make an adapter for the external size), as the internal size is what controls the airflow.

The most expensive carburetor is the wrong one you attempt to modify.
If you truly believe "one size fits all," try walking a mile in your spouse's shoes!
