Great choice. Big tank, pump and big slow motor. Big bucks I imagine too. What's the current rating on that motor? Brand?
I bought a similar used Saylor-Beale off CL some years back--love it!

Be careful not to undersize the air lines and do use some cooling, drying and filtering. The potential flow through a line basically doubles between 1/2" and 3/4" (area of the circle) so that's something to keep in mind.
I don't like air lines that run up and down leaving lots of places where water can collect. I like the water to have to be flowing out or back to the tank. Of course I have a 2 car garage so one end point with filter/dryer/regulator.
Also, get a little gate valve and some small pipe and fittings so you can purge water easily and often. Just blast out the air from the bottom of the tank a few times after the air has cooled.

But you had another so you knew all that crap...
