I would like to add some additional details to my original post.
I have, what I believe to be, the original engine from 6S2328. It is now installed in my car, 6S1291. The original engine from 1291 is on a stand in my garage. I have verified, through Mr. Pardee, that the Ford and Shelby VINs for for both cars correspond correctly to one another. Looking at the history of both cars in the latest registry makes the engine swap somewhat possible, geographically anyway, I believe. I am happy to just leave things as they are. The car is a nice driver, not a show car. However, if the current owner of 2328 is interested in reuniting the engine with the car, I would be willing to talk about it. I just thought that I should get this information out there in case someone on this forum had any knowledge or information regarding 2328's present owner or whereabouts. Some information that I received states that the car could now be in the Netherlands, but I haven't been able to gather anything further.
Thanks for your time guys, I hope that I have gone about this correctly. Please PM me if you have any information or other comments.
