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.
