Just got a 250C 130.923, looking for any information and specs on this car. I have been surching for information, not really finding any.

I've got one sitting out front that I've been trying to sell since March.

There is a 250C Yahoo group.

The Coupes are basically the same as the sedans except the rather obvious difference in door count. The roof line is lower, the seats are a bit lower and I don’t think any of the glass interchanges.

The M130 engine is the 2.8L SHOC twin carb, the 280C is the same car with the M110 2.8L DOHC single four barrel carb and the heavy US bumpers.

A CD containing nearly all the repair manuals is available from MBUSA.

Thank you both for the information.

The 1973 280C had the chrome bumpers!

And to call them the "same car" is a stretch. Besdes the engine, different:

- tramsmission
- ignition
- exhaust
- emissions
- various trim items
- frame components (e.g. no bracing in engine compartment)
- battery location

I figured with that with the different engine that the auxiliary stuff was different also would be obvious but sometimes I assume things that aren’t general knowledge.

My ’76 280C had the big bumpers, different mirrors, vacuum door locks, the drive train was completely different and didn’t have wing windows but parked side by side, the two cars are the same. Except for the tail light lenses. And the steering wheel.

PS, bracing in the engine compartment? Neither of my W114s have had bracing that I remember. I picture the triangulated braces in the '65 Mustang.

You would probably note that bumpers on pretty much every US car in 74' changed due to changes in bumper regulations for US cars.

..I also have a 427 Cobra replica with an aluminum chassis.

Can you please tell me what the "280 S/A" on my head casting means?
The engine reads 130.923-12-005234 The Head reads 130 0116 2001 then in big number the 280S/A

My '72 250 and 250C also have 280S head markings.
Starting in '70, supposedly because US emissions regs were beginning to rob horsepower, and US buyers were demanding power accessories and automatics, the US market W114 250/250C cars got the carbureted M130 2.8 SOHC engine from (or similar to) the contemporary 280S.

The engine compartment braces on the early W114/W115 cars were a pair of one-inch diameter steel tubes welded to the center of the firewall and angling down to each frame rail. They usually have cables and wiring harnesses strapped to them so they may be easy to miss. If they aren't on the W114 280/280C cars, they were probably eliminated because the larger head on the M110 DOHC 2.8 engine, obstructed the firewall attachment points for the braces.

Happy Motoring, Mark

I think it means it is a non-injected 2.8 head. The injected versions have "280 SE/A". I am not sure about the "A" but it seems to have been added to later heads - circa 1970.

As far as I can tell the "A" is for automatic. Mark that is what I thought I was also. Once again thank you.

Is their any wiring information out there for this car? I'm not finding a whole lot of information on the M130.

The Haynes 230,250.280 repair manual has an emissions wiring diagram in the carburetor/fuel-injection chapter, for the 70-71 carbureted 6-cylinder engine.
Same book has a main wiring diagram for the 230/8 and 250/8 in the electrical system chapter.

Otherwise, you'll need to find a copy of the factory Mercedes W114/W115 chassis and body service manual. Curiously, in my copy, the schematics for the carbureted W114/115 only show the standard point ignition used up through '69. The transistor ignition circuit is in the 250E circuit diagram for a fuel-injected version of the W114 that wasn't sold in the US!

Mercedes used to include a wiring diagram in the back of their owners manuals, but that frill was probably eliminated by the late '60s.

Happy Motoring, Mark
