If you want a good performance pop with decent street manners and a lopey idle, I would go with the Vinci street/strip cam #047 (210/218 0.531/0.531 112). It will work well with the LS6 springs and stock heads.
Or, you could go with Vinci's Asp-Kicker cam #062, which is the same grind with higher lift (0.551). The LS6 springs would also work with this cam.
Here's a sound clip of their idle:

I don't know if these cams have any advance ground in. If they don't, I would install either one with 107-108 degree ICL.
Sounds good in the Vette, would it perform well in a 4.8 or 5.3 with stock heads and sound that good?
