However, the cowlings are different, and the nose is the ditinctive Douglas/McDonnel Douglas narrowbody shape

From an earlier quote, the problem with the DC 8 is the modifications it had. The wing cowlings, winbg sweep, engines,length, speed were all continually changed. It is like making a new plane altogether for FSX modellers. The 747 classics would be great. I would like to use both cockpit versions of the 747. The engine variants, range and other things would be difficult though. Also, for the Frenchies (not trying to be mean, just British) use Google translate if you are having language problems.
