734 Max Range?

I have been tracking the AS ANC-LAX flight prior to taking it, and have noticed on at least two occasions that a 737-400 was subbed for a 737-700 on this route (once in each direction). I guess I'm surprised the 737-400 has sufficient range to make the trip non-stop. The distance is 2345 miles, although it must be routed along the coast as a non-ETOPS aircraft, this adds another 50 or so miles. Isn't this pushing max range? I know US used 737-400 for some transcons, although I believe these aircraft had auxilary fuel tanks. I know AS had a 734 flight on ORD-SEA (1721 mi), and the westbound trip actually had to make a fuel stop on one occasion I can recall due to very strong headwinds.
