I don’t know what a 294 oil pan is specifically for, and judging by the number of replies on this topic, not too many other people do either. Is this a stock a-body pan? You can’t go wrong using the pan that Mopar put on from the factory on a stock engine for the year of your car. I’m not aware of many changes on the K frames from 72 to 73, but maybe somebody else can chime in.
