350SL intake on #80SL
I have a intake that is alleged to be from a 350Sl. The number cast on it when I received it was 117 141 0201. My initial reaction was this was from a 450 SL but thought maybe the bulk cast and mill the head mating surface to the particular engine. I can't find on the search engine any info on this. Does anyone know if this will bolt on to my 380? I'm aware of the holes for the air pump. Im just talking bolt on. information would be greatly appreciated before I have to cut the two apart and weld them back together. I need the throttle body mount where it is on the 350 for a project Im doing.Any help would be appreciated.

The first few months of USA R107 production were badged 350SL (I own one) but the car actually have a 4.5L M117 engine, not the 3.5L M116.
Your 380 is an M116 and would have been CIS, a 350SL would have been D-jet if its a USA M117 intake you have. I don't fully understand what you're asking, but there are M117 350SLs because the early cars weren't badged as the convention of the time would suggest.

Casting numbers can be confusing. They are not part numbers.

I have a project iI want to build the injection is irrelevant. I just want the straight runners off the D-Jet manifold. and center throttle body location. The person I bought it from said it was off a 166 350( I am aware the first one was a rebadged 450) but when it came through it had a 117 Part number. So I need to know if the one I have is a bolt on or do I need to cut the two manifolds apart and weld them together.

right. I'm not concerned at all about the throttle body or the air pump holes. Just t id it bolts to the heads of the 380. I can't find the answer online as to weather or not Mercedes made one casting and machined to fit either engine (the sensible thing to do) or cast two different manifolds with different runner lengths. I'm putting together my own fuel system so Im only concerned about the manifold bolting to the 380.

Excuse my big sausage Link fingers. I meant to type m116. I'm not concerned about the throttle body or any ancillary parts. My only question is does anyone know if this manifold will bolt onto a 1982 380SL without machining.

The inlet ports of a M117 are 41mm (1.6") wider apart (laterally) than those of a M116, because the deck of the 117 is 29mm taller than the 116 (245mm vs. 216mm).

Thank you. That information should be helpful. |

There has been one parked in my garage for close to 10 years now. You actually helped me get it running in a thread many moons ago along with Graham and MeltedPanda.

So the OP has a d-jet manifold supposedly from a m116, but sees a "117" stamp in the casting. So we don't know whether it's from a 3.5 or a 4.5 and we are trying to figure that out.
Why don't we bust out the tape measure and determine the width? (Sorry I'm not near any of my 3.5 or 4.5 cars right now to provide a comparison measurement.) Then the second question will be what needs to be done (if anything) to make a d-jet 3.5 intake manifold fit into a 3.8 m116 engine (k-jet by definition). I personally do not know. I do know that carbou engineering in socal modified a 4.5 d-jet intake to work on @pearson 's modified 5.6 m117 in his 560sl. I also understand that you should be able to bolt 3.5 d-jet heads right only a 4.5 d-jet to drastically increase the compression ratio (but don't really know). And what's that really get you? More power? Certainly not higher revs of a 3.5. And certainly the requirement to run premium. :-) I'd be interested in hearing more about this project since I've got a euro 3.8 1983 380se that really seems to have some grunt to it. Nice engine!
