I have written a few replies to threads on W111 and W108 V8's (quite similar), so you can do a search for them. There is also a good thread on W111-W108-W113 mods.
The 350 motor would work fine, but I am afraid there are not many options for a manual trans from MB. You would have to try to find an MB 4-speed (there were a few 5 speeds, but rare as and $$$) from a V8.
The 107 rear end won't bolt up - I think the mods thread has a pic of a finnie with one installed though, but it is all custom fabrication. If you want a simple solution, find a W108 4.5 V8 and use the engine arms on the 350, 450 or 560, the trans, the diff, steering box, engine management, fuel pump/filter/accumulator, brakes, master cylinder and some of the wiring.
The short nose car will need a custom radiator for a larger V8. A modern, more efficient one with the thermo fan should be ok. My car is running too warm, but i think it is due to a suss water pump impeller.
So do a bit of a search and if you still have questions, sing out. This will not be a quick project but if it is something you really want, then it is definitely do-able. Have a look through my photobucket page for some pics of how I went about it - note though that you don't need to replace all of the trans tunnel like I did, only part of it.
