Hi All, We all know some people were not satisfied with their engines, o broke it, for any reason. A few, above all in Europe, had their engine replaced AT the Factory in Modena. So, the Factory put inside new engines. What about the chassis serial number stamped for example at the upper front left side on V8 engines? (I don't speak about the inner engine number that we can find in the inside too). I understood that there were 3 variations : 1- original chassis nuumber stamped on the blank engine, 2- not existing chassis number stamped to avoid the risk oh having 2 blocks bearing someday the same chassis number, (example AM115/5000 fo a new engine in a Ghibli) 3- they let the block blank, w/ no chassis number at all. Question in the question, beacuse we are expertising the case down there : 4- did any engines ready to fit with an already non existing chassis number stamped ? I explain, would have it been possible to put in an Indy or Ghibli for example, an engine aleady stamped with an AM107 non existing chassis number ? In the present case, the engine is stamped with an official Factory replacement number : AM107/A * 1600*, and is NOT in an AM107 model. I was confirmed by one AM107 Specialist that the "A" was used to state Factory Replacement Engine". Hope I have been clear enough. Gazie Mille.
