I have a really Nice 1983 380SEC that was converted to a 1986 300SDL for sale! Now It does need some engine work I think it mite need a valve or 2 because it's smoking pretty bad and missing. Now I changed the pre-chambers and injectors it helped a bit but not the answer. 3 of the old pre-chambers were burnt off and I'm sure it hurt something on the way out. If any one would like to take this project over email me with offers. Thanks Nugenti@aol.com
