What is involved in putting a 617 in a '91 350SDL
I got a line on a '91 cream puff of a 350SDL, and already have a 617 in nice condition. What is involved in putting the 617 in the bay and what parts are needed? I assume because it is a 126, most of the stuff from another 126 300SD would transfer over. Anyone done this before?

Might be better to buy a rusty 350SDL (like mine) and put the good motor in the nice body.

I am going to stay away from the 350. A 300 (6 cyl) maybe. I know a 617 may be a little under powered, but an '85 with a 617 is not a snail either. The SDL can't be more than a couple hundred pounds heavier than an SD, so the 617 should do OK in the SDL.

Swap hood and deck lid over, along with motor, trans,crossmember and it should be simple. I've seen it done before, never myself though.

Why the hood and deck lid? The 350 is near perfect in every way. The paint is like new. Garaged all it's life, and has about 100,000 miles on it. If a different crossmember, that tells me that the trans is moving forward? If so, the driveshaft would need to be lengthened as well?

I just figured out that the trans will have to be changed as well. The 60X trans has the starter on the opposite side as the 61X trans. It looks like I will have to look for a donor 603, or better yet a 606. The 617 would be too much work since I don't have a good trans to go with it.

You might be able to try a V8 front half from a 300SE (or another Short WB w126 sedan with a V8), or possibly even something off an SEC? Would have to check measurements but there's a good chance another MB driveshaft would fit. When people swap 617's into SEC's they use a MB driveshaft but I don't remember what model.
I prefer the refinement of a good running 603 though so I would find a nice running 3.0L and swap it in there. I've seen some cheap W124 diesels recently so I think it's plausible to find one for not too much $$.

Why? Don't want more power?

They are hard to find without issues, and the 603 (3.0) is easier to find with little or no issues. I am going to scrap the idea of a 617, as I don't have a matching trans, and the trans in the 350SD has low miles on it.

An updated 3.5 is arguably less problematic than a 3.0.

Where would I find one of them without buying an entire car?

Junkyard perhaps. Look for the tag on the bellhousing
If you decide to pass on this car let me know, as I said my motor is perfect but body is rusty. I'm at the point where I either need to do structural repairs or move the motor into another shell. -J

A three litre 603 with the 3.5 head you already have increases the resale value of the car. Same block with a reduced bore for all practical purposes.
The power is better and the fuel milage as well in comparison to a 617 change. The noise level is reduced to some extent over using a 617 as well.. No real problems exist with this change either. Solid bottom end 603s blocks are out there. Also if your 617 car is decent it will remain so or you could sell it to fund the change with money left over if doing it yourself. |

Mmm I'd like to have a nice 91 350SD to dump my one 300SD's engine and trans into.

Is there anything wrong with the 350 that's in there now?? Not all of them bend rods... I really like the power and how smooth mine runs.
