A new engine will normally do that as it breaks in over the first couple thousand miles -- I doubt Slick50 had anything to do with it.
There are a lot of "snake
oil" additives on the market. Your best bet is to use a quality
oil from the get-go. Solid flat tappets need more
zinc/phos. than a hydraulic, but there is no downside to having a high
zinc/phos. content with your hydraulic cam
unless you have a catalytic converter (which 99% of Cobras don't).
