Advance Timing
you said "You can run more then that and the gasket will hold just fine " then said your truck holds fine at 21* of timing, implying that it is ok to run 21* on every truck with stock bolts and no o or fire rings.
More then 16º also includes 17º and 18º and 19º. As I said, 21º was just an example, not that every truck should run it. To say that you CANT run more then 16º on stock gasket and bolts without the gasket going is not true.



isn't that the truth
