617.950 is listed at 115HP and the .951/2 are 123/125HP. If
stroke/displacement are the same, what did they change that increased the

Depends on who's measuring them and whether it's a DIN or SAE
measurement. Mercedes isn't even always consistent in the figures THEY
publish. I don't think that all of the block castings were identical,
but I don't believe that's the most relevant difference. I'm pretty sure
there were cam differences, but there may have been other small
differences as well and they may not all be associated with the chassis
model changes, but may have slowly come about over the course of
production. The 950, 951 and 952 designations specifically relate to
engines that were assembled to be installed in 116, 126 and 123 chassis
cars respectively, but all 952 engines (or 950, or 951 for that matter)
were NOT identical (although all engines with one model designation
could usually be interchanged without much trouble)!
Lot's of people felt that the 617.950 engine in a 116 was faster than
the 617.951 engine in a 126. Emissions requirements WERE different!
