1. 777 has 3 wheeler bogeys while 340 has 2.
2. 777 engines have 70-90,000 lbs thrust each, 340 has 34,000 lbs each.
3. 777 allows pilot to overight computer, 340/330 gives computer more control.
4. 777 has asymmetric thrust system, 340/330 doesnt.
5. 777's wings are more rigid, while the 340/330 is more flexible.

The Asymmetric Thrust System is a system found on the B777. It's used when one engine fails on takeoff after V1. When activated, the computer (again its the computer) would then calculate the necessary reductions (or increaments) in power necessary to drive the airplane into the air, and perhaps keep it level.
Perhaps anyone with more technical knowledge about this could help?
