767-400 Thrust Available
With the 767-400 using the P&W's PW4062, the same ones used by 767-300s. Even with GE CF-6-80C2B8F at 63,500 lbs, it's only 200 lbs of additonal thrust compared to the P&W's. Wouldn't this significantly degrade the -400's performance ability compared to other 767s? Or is it just that the other 767s are extremely overpowered.
Maybe even 76 drivers out there who have flown the 400 and the older models?
Thanks for your help.
