It idles fine - I just can't stab it off the line from idle. That's when I have the problem with the stumble and pop. Also, I can definitely feel the difference between the 1mph idle vs the stopped idle. He said he is commanding all the airflow he can is I think what he said. He said he could goof with some other stuff to make it work, but that would mess other stuff up and didn't want to do that.

Looking at your dyno I am really surprised you dont carry power higher in the RPM range. That's a big cam. Even with the 4.1" stroke I think its signing off a little early. I mean you more or less hit your peak HP at 6k.
I guess its hard to know how your drivetrain is effecting that though. Maybe the tires make things weird on the dyno as speed climbs.

I've been doing a lot of reading on the subject and it seems the LS3 heads don't like the bigger cams made for the cathedral port heads. Something about how the intake and exhaust ports don't flow at the same ratio so the valve events have to be reconsidered.
It's all voodoo to me, and to be honest I think I'm going to have to test out cams to see which ones I like better. My setup is not like most - everyone seems to have big cnc heads on their strokers so maybe that's another issue I have to address and bite the bullet to make more powa
