I checked out some quick bread recipes (not banana) that baked for 45-50 minutes (can being 2/3's full) at 350 degrees. One used 20 oz cans and one called for one pound coffee cans.
This recipe for Banana Bread below calls for 375 degree temp for an hour and a quarter (75 minutes).
It seems to depend on the recipe but that gives you some guidelines.
I would test with a piece of dry spahetti so you can test closer to the center. Banana bread is so moist usually you want to be sure it is done in the middle.
I made some quick bread in cans years ago but they were small soup cans that I used.
