904 vs 727?

and I have a hard time getting 100k out of a 904/998/999, in daily driver steady cruise, back n forth to work, grocery store etc with everything stock, even on a 318 2 barrel.... and regular fluid changes, etc... that's why I call em "nasty 904s"..... I've swapped from 904>727 before many times, but never the other way around, not on one of my own vehicles, anyhow....
I just gave away the /6, 904 I had, yesterday..... to a guy that races a 12 sec /6 car, figured he could use the additional spare.... if I somehow kill this 727, I will consider what's available at that time.
