310, that's all? Were you heavy? Or the wing just quit flying?
New engine. Same wing. It would be slow, but the engines could get you into the high 30s/low 40s no problem.
We generally are within 15K of max takeoff weight and can't get above FL340 until a few hours in. The good thing though is that the engine is so damn efficient that the difference between doing a crossing at FL360 and FL260 is only about 1500 LBS of gas. In the winter we've been getting a block between 22 and 30 some trips just to find smooth air.
