Hopefully more experienced LT1 guys can chime in with how much is acceptable, shoot, they have a pretty aggressive timing table from the factory due to the reverse cooling so I creep up on it and do a lot of logging.
The stock is in the very first message of this thread. Mod list is there too.
I've disabled egr, but hadn't removed it manually. It is installed, but not working because of PCM.
