What has anyone experienced with ignition timing? I use 26 - 27 degrees total above 6000rpm, generally finish line rpm about 7600-7700. I have been told that is max timing to use because of detonation above 27*. Anyone run 28 to 30* of timing and did you pick anything up? Thanks, Dyno

How did you do the Holley system & not get the factory functions of the car messed up, I have been trying to find a set up that will have wide band o2 fuel control & tuning on my 2020 T/a 392 ?
