I think the slower cummins came with the 88 series, but you can start it up and check the high idle rpm. I just bought a 91 with the long sleeve and it is more combine than my 87 1660. I have to add a chopper, but the price was low enough to justify buying without the chopper. The longer sieves appear to be a really good idea - I rarely overloaded (I kind of wonder how the 80 series got along w_ short sieves).
