Re: Driving on the freeway
Personally, I like to stay under 3000 rpm on the highway. That rpm with a 4.11 rear gear and 29" tire will be 63 mph. Above that rpm it just feels too busy to be comfortable for my taste. My '41 Merc with 3.54 gear and 29" tire is just under 2600 rpm at 63 mph and really runs nicely there.
This isn't to say you can't spin 'em faster...but I prefer the above.
