The previous engine masters magazine put one in their moderate built 496 and they like it, if I remember right it made 6XX (low ut one on600) hp by like 6k RPM. It was not the largest cam they could get either.

I can give you details tommorow if you would like.

Looks like nice off the shelf cams.
