I have been told you also have to swap the om603 oil filter housing or space the 606 oil filter housing out 20mm but that is hear say from another w126 owner that did a 606.962 swap in a 350sdl I have a 300sdl and have not gotten that far yet.

I've since answered my own question re:cruise. The '95 W124 w/NA 606 had mechanical cruise, so I should be fine there.
I guess the big one is, if I can reliably meet my power goals with a 603, why bother replacing it with a 606?
