I think it comes down to a few things. If the Windsor block in my Cobra was swapped out on the first build then Robert's Auto or someone at Robert's screwed me and is probably laughing their asses off.

If the Windsor block was installed at the factory its easy to assume a very unlikely set of circumstances allowed that to happen.

Sean Hyland stated Windsor blocks were sourced if the Romeo blocks were low on production. In any case, I have confirmed all 03/04 Cobra engines, regardless of where the blocks were made did get assembled at the Romeo plant by hand.

My engine builder is adamant that no Windsor blocks were installed in the 03/04 Cobra's at any time. I want to agree but need to see it in writing from a Ford authority.

In any case, I don't think it will affect value of the car. Its surprising to discover how mysterious Ford is and difficult to understand why direct answers cannot be had from them.
