Quote: What fuel? At that compression probably better than standard pump swill. If it doesn't ping, run it to manifold vacuum.It will give you the extra timing for a better idle/mileage and automatically goes away under heavy/full throttle.
my build is close to the OP, even the 11.2:1, I run 38* all in by 2200 and NO vac advance. But I also run meth/H2O injection to reduce detonation. A tad OT but how do yo uhave the 6-pack set-up?
