Yeah, I was hoping to do the same thing with the spoolinator. Install it, ask for a conservative tune, and reinforce the block with drop-in pistons. As Prime are far more of experts than myself, I think it would be foolish of me to tell them to do something other than their recommendation. Once IAG responds, maybe that's another option. I did all the things that to my knowledge should help the block: killer b pickup, AOS, ELH, and I'm anal about my real-time monitoring, checking oil, and oil analysis.
