What is a "reasonable" speed in a Model A for one to get "reasonable" engine life?

I'm inclined to believe him as he has decades of Model A & T experience, pours his own babbits, etc., but I'm curious what the group's experience is on this. I will probably drive the car 1,000 to 2,000 miles per year, so even 30,000 miles will take a long time. If I get 20 years out of this engine that should be plenty.

Who did your rebuild?
