I am looking to advance my timing in my pretty stock 5.0. I understand the genral idea of how to do it from what I have read on here. I just wanted to make sure should I unplug my MSD while doing this? I know stock is 10 and I should set it around 14? I know I will need to run a higher octane. Also I know this a dumb question but how can I identify pinging? Just not sure what it is engine misfire or what? Also any tips from everyone who had done so would be great.
