This is actually what I am running right now with 13PSI on my 8.5:1 SVT. Anyone have anything to add? Should I use more spark in areas? Less? How does this look compared to you yours? I do not have knocking, but then again, the car feels abit slow, so I believe I can add more spark. AF is ~11.0 from 3000 - 7000RPM. Any input on this is helpful.
