Just finished and installed my Dart LS Next build and need help with base timing parameters. I have read and watched lots of tuning videos recommending an idle timing of ~24 degrees and all in at 31% by 3500 rpm. Given the intake and heads I don't see a lot of reason to spin it past 6500 rpm. I am not intending to race, cruise and show mostly, some burnouts of course. Any insights or recommendations are greatly appreciated.
