For what it's worth, more 427 block equipped Cobras had center oilers originally, than side oilers. I believe most of the originally equipped 427 side oilers were in SC, Competition and maybe a few late street cars. A center oiler would be more "correct" for most of them - if anyone was striving for originality.

I wonder if Cobra motors had any stampings on them that tied them to a particular car - I don't remember reading of any? My impression is that the Shelby crowd doesn't get as excited about original equipped motors as the Corvette guys do.
