I'm very fond of good FE lineage myself and have heard similar stories. I believe it was unusual for any kind of numbers to tie the FE to any particular Cobra. Having said that I have seen the CSX # stamped into an intake manifold but I don't even think that was done to the cars original motor. There is sooooo much stuff on e-bay that a friend told this guys uncle in law that this part is from a real Cobra. It's the stuff of Cobra legend if you ask me.
