I don't know, I suppose it could have been Chinese. Is there a way to know for certain? On the Chinese Walbro fuel pumps for example, the lettering is laser etched on the Chinese pumps and stamped on the actual Walbro units. Is there a tell tale sign on the MSD units? However, to be honest I haven't heard of the MSD units being copied and released by an inferior company, but it's definitely possible. Have you ever heard of this instance?

In retrospect, why don't you PM the answers to the MSD opti questions. That will help keep from mucking up the thread with non-pertinent discussion. Or, maybe you could post the answers here for others to see. That way, everyone's knowledge grows and the forum benefits from it. Either way, condescending tone aside, thanks for the information/discussion.
