Do the different powerplants affect the 767 performance significantly? It has got to be costly to fly a such a diversified 767 fleet in terms of engines.
I'm going to have to side with you and the GE website about the -400s having the B8Fs.. Boeing doesn't even list the B7Fs as an option for the 764. I'm thinking my info must be wrong. Thanks
Caution wake turbulence, you are following a heavy jet.
Weirdly, GE claims that they sold B8Fs to both DL and CO for their 764ERs.
While I can't talk for CO, DL 767-400s DO have CF6-80C2B8F powerplants, at least according to my training manual and the AMM. I'll look at the data plate on the engine the next time I get a chance to work on one.
