STOCK LFX cam grind specs

I've been searching for information for the STOCK cams installed in the LFX engine. Spent over a week searching HPtuners forum and Google in general. The most specific thing I found is that LFX intake cams have a "longer duration" than those in the LLT from GM techinfo. What I'm most interested in is the actual durations as installed. Other specs like lobe lift would be nice but not needed as much. Before anyone comments; Yes, I know I control the separation and No, I'm not going to "just screw it and swap'em for some Mace Cams." Thanks Guys.

I would also like to know this information. It's hard to blindly modify the cam tables when you don't know the stock duration. The factory tables are all over the place.
