5.7L Ignition Timing Table - Feedback

Don't know specifically what numbers should be in there, but some things to keep in mind:

1. Modern engines with great squish and multiport EFI (especially dual plug!) have very efficient and fast burning heads. Mid 20's can be A LOT of timing, especially around peak TQ.
2. As you turn up the timing on such engines, you will start losing power way before you get audible or sensor detected detonation.
3. Doing a spark loop test on a steady state dyno is about the best $$ you can spend in this regard.
