268 Voodoo cam rpm and vacuum

I'm running a Lunati Voodoo 268 duration (60403 If I remember correctly) cam in my 360.
I'm pulling around 11.5" of vacuum @ around 875-900 rpms idle in park.

I know this is a fairly common combo.... What are you guys getting for vacuum and idle RPMs?
I run a Comp 262 XE and have 15 @ idle 850 rpm .
