I remember Dugan or one of the other tuners doing a run of these. One was in muscle mustangs it was a black or dark blue cant remember The title was the Cobra Ford should have built or something like that. They faked certificates and all. I remember thinking wait 10 20 years when someone ends up with one of these and thinks its real.
Someone needs to dig into one of their boxes of old mags in the basement and find that issue. I've kept all of my old mags but didn't start "collecting" or "not throwing away" until the end of the 90's.
