A 2.73 with a th350 will be great for the highway. But just OK for relaxed driving around town.
Years ago, I had a 350/350 and 3.08 gear combo with 30 inch tall tires in a 4000 lb ride. One the highway I was wishing for a lower numeric gear and around town a higher gear. So always a compromise with a 3 speed trans.
Maybe a 4 speed would do trick.
