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 HP? Are the shortblocks identical? TIA all.
In addition to what has already been mentioned, the w116 300SDs used the earlier AirResearch turbo units. I believe AirResearch was later purchased by Garrett, but don't know that for fact.
