There was an article or series in "Classic Trains" by Kalmbach at some point that summarized the development of the E-series passenger engines. It did explain each upgrade in layman's terms.
My memory is that that the article stated that the change in orientation of the Prime movers was done in the E8 model. The E9 was an upgrade to HP and possible prime mover tweaks as mentioned. But I thought the major change to the internal layout was between the E7 and E8.
But this is all from convoluted memory, so don't crucify me if you find otherwise.

You were correct, thanks!
