This engine seems to be a clone.one in in my garage in Italy and the other one is installed on a car seen autioned online somewhere in US. On the picture there's the chassis number of the US car auctioned. Note that there'no factory number on This engine and it doesn't seem to be grinded or deleted in any way.
