M110 in a 450slc

Hi, i'm intending to transplant a M110 and its transmission from a 280slc into a 450slc, they are both K-jet injection engines from 77/78. Can I check what other parts would require to be transplanted from the 280 into the 450? Fuel distributor, differential, manifolds, air intake, what other things do I need to take note of too? Thank you all.

Drive shaft. Not sure what else honestly. Might want to consider the front springs.

You will need everything from the front of the radiator to the differential minus brakes and subframes, gearing is different, sounds like a lot of work.

If a manual trans you will need peddles, clutch master cylinder etc.

Thanks guys. They are both automatics but I know it's still a lot of work. Problem is the 280slc I have has a very new engine but an extremely rusted body. The 450slc has a toasted engine/transmission but is decently rust free with all wirings and stuff in place.

Other than being a lot of work the only real hindrance would be engine management. Whether or not the M110's ECU and such will plug and play in the 107.024 wiring harness will be interesting.



Keep us posted.

Classics are almost always the most valuable when kept original. If a 4.5 is toast, I'd probably want most to replace it with an identical engine. That way all the same manuals and gasoline grades, etc all apply. Engine swaps make "frankenbenz" even if it's MB to MB motor. Hopefully if you do the swap, you plan to keep it forever.

One other thought... if "upgrading" a motor, I'd probably recommend the pinnacle for the body class or better. The euro 5.0 m117 was the pinnacle for the 107 chassis. 240 hp. I'd be looking to put in something like that or better unless I planned to keep it forever.

That's just my opinion. Everyone has one.

I totally agree that classics should be kept original. I hope this frankenbenz that I am attempting does not offend anyone. Actually, the transplant is a means to an end as I need 1 of the cars to be road worthy as soon as possible. Then I can hopefully restore the rusted out 280slc shell after it has been stripped. That may take a while if I don't give up first. Then I would probably switch them back to their original state. It probably sounds extremely ambitious if not, ridiculous, but that's what i hope to achieve at the end.

I am not a big believer in preserving everything. It actually serves my purpose if you turn it into a tractor pulling rig. It would be one less and thus increase the value of mine but it would also be a lot of fun.

If you are pulling out the M10 engine intact....then most of that stuff will still be attached.

Grab the silver box on the driver's inner fender...the ICM....ignition control module....and also the fuel pump relay that is mounted above the fuse box. I don't recall if the relay is a silver ice cube or a black module for your particular model years.

Somebody mentioned front springs.....I actually have 450SLC springs mounted on my 280SL.....stiffens up the ride.
