big block cam id help?? need answers from big block guru

a few years ago I bought an already built 500 stroker and it was a few years old then, engine still hasn't ever been cranked but I don't know where I put the cam specs for it and shift point info and all that and well all I remember is its a mechanical flat tappet with a .600 lift, and was wondering if someone knows of some mech flat tappet cams from big blocks that had a .600 lift and about what duration and shift points would be and possibly manufacturers I've searched online but no luck yet with any sites I've checked so i'm assuming its an older cam that may be discontinued being most aren't really putting out mechanical flat tappets anymore or maybe i'm looking in the wrong place.
so if any of you big block guys can tell me an idea of what kind of duration, rpm range, possible manufacturers i'd greatly appreciate it thanks
