That's what I'm getting at. As the covers in 275's post have Ferrari on them and it is a rep engine. If you see my earlier post I was wondering about branding the engines. Glad to hear there is a way to tell them apart. But it is a sad fact that people will cast with those marks some day and sell repros as real. That is the part of repros I don't like. If you are paying for a real part you should get it.
