Duration is supposed to be 211/230 and lift with the 1.8 rockers is .591/.591. I haven't seen any other specs beyond those.

John, the closest I can come to your valve events is 211/230, 120LSA 123ICL (-3). Sound about right? It's got about -20 degrees of overlap at .050" which compares to the '02 LS6 cam with -24 degrees of overlap and the LPE GT2-3 cam with -20 degrees of overlap. For further comparison, my Thunder Cheater Cam has nearly identical exhaust valve events, but the intake lobe has the valve closing at 43 degrees ABDC which works better for a 346. 49 degrees of intake closing point would make this cam really lazy on a 346, but it's probably the reason it will rpm with LS7 heads and 427 cubic inches. Good job GM!

I would love to see what a 244/252 112LSA cam with .615 .610 does in the LS7. I imagine 50-70rwhp gain with just a cam.

Unfortunately I couldn't tell you! The 0.050" lift spec's I quoted were the ones that I received directly from GM.

Do you have the specs at .006? Also, again, is it available and how much?
