UA 874 is a 777.
United Continental doesn't always display correct information in the schedule change boxes.
Best thing to do is to start a search on a new trip for the flights that you've been rebooked on to figure out what the planes/meals/etc. really are.
That's what's really operating the flights. The United Continental website just isn't displaying it correctly.
Once you hit "Accept" it should display accurately.
