Default LS9 Camshaft

Anyone know the spec on the ls9 cam? also is anyone runing this cam? i was told by LPE to run this cam in my truck, instead of the GT2-3 that i have read so much about on this forum. They also told me that the GT7 is not in production any more due to it being almost identical to the LS9 cam. Any info is appreciated, mods are in my sig.

I wouldn't recomend that cam with a cathedral port head. That split is more for an L92 style cylinder head. I'm also not sure if that cam has the cam sensor reluctor on it since the LS9 is a Gen IV.
