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 ? Race car only. None of the factory computers are used.
