I recently purchased my second w111 fintail Mercedes. it is a 1963 220Sb,this car was in the process of being restored and has beautiful interior wood and excellent or redone chrome except what is missing. It is missing rear fin trim and taillights unfortunately and the passenger seat, i believe the guy i got it from got it at an estate sale and didn't get all the parts with it. but with almost zero rust and 98000 original miles ill deal with that.
The missing stuff isn't that difficult to get, except nice rear tail lights for a 220S are pricey.
I have a plan.
The first thing is the engine. it just happens that the m110 2.8 litre dohc(dual overhead cam) 6 is basically the same block as the m180 sohc that is in the car and should bolt right in with the original mount arms,but its 182 hp stock and has simple k-jet injection that gets way better mileage too.
I had no idea that the block from a M110 was related to the block from a M180. I've always thought of the M180 being related to the M114, M129, M130, etc. But whatever... Things to consider - If you are going to use a manual transmission you might need a flywheel from a manual transmission M110 engine, which I would think to be quite rare in the US. I'm not sure I'm correct on the need for this but I am sure I'm correct for this on an M180, M130 engine. You are also going to need to come up with an oil cooler solution for the car as they were handled completely differently between these two cars.
I think i can make the power steering box from a c107 slc work in the w111 ...
the vented front discs are pretty much a bolt on from what i have read which is awesome. i'm hoping that the front sway bar is bigger and useable for me too. i have a disc brake rear axle from a w108 i bought from fonzi also.
I'm not even going to comment on the steering. As for the brakes, there are more issues than you might know. First of all, your 63 probably has single circuit brakes with front disks and rear drums. I have a 63 220S also and was told a load of crap about bolting on later vented calipers and everything would be just fine. WRONG. And I was going from a W108 which is VERY similar. Maybe your car is different but on my car the mount points for the calipers are NOT the same.
Next issue is how you deal with a single circuit system and add rear disks. I don't think this is straight-forward by you might be able to do it by adding a proportioning valve to the rear and using the later rear axle.
If you do some reading you will find that conversion of a single circuit brake system to the every so slightly later dual circuit system is a major PITA. Including changing and welding things on the firewall to accommodate the completely different location of the brake master cylinder and the booster.
So the main problem i still have is that the rear end is a 4.08 ratio, the car the motor and four speed trans came out of is a 3.59 so highway will still be screaming. After doing some research and some measuring i believe i can put a mustang t5 overdrive trans
can anyone tell me if the m110 and the m180 are neutral balanced flywheels in case i need to swap them?
I can tell you. The M180 engine has the crankshaft and flywheel balanced as a single unit. The flywheel alone from the M180 is WAY not balanced, as is the engine. As designed. The M130 engine has a crank that is balanced independently and a flywheel that is balanced independently. I can't say for the M110 but I would suspect it to be the latter. So I think you will need a M110 flywheel that is independently balanced and for a manual transmission car. I am 100% sure that you can't use the M180 flywheel unless you have it balanced to be neutral, which is a hell of a lot of grinding.
Good luck with your project, I highly recommend a lot of research before you go too far down this path.
