Guest jeff1216 Posted November 28, 2003 Share Posted November 28, 2003 I have a junkyard dizzy in my 78 280..... My advance is not working so I thought it would be a good time to pin the dizzy at full advance.....I plan on using a machine screw to lock it at full advance......My question is this. I have a timing light with the dial on the back. At what RPM do I need to set the timing? What setting do I need to set the dial at on the back of the timing light? How much before top dead center should I set the timing to? And last but not least...... Will doing this improve the performance of my car?

Clifton Posted November 28, 2003 Share Posted November 28, 2003 I fit's a street car that has to pass emissions I wouldn't do it. Running 38* at idle is alot , 22* on a turbo car isn't as bad. If it was a N/A car I would just fix it. On mine I removed thje springs and wired the weights together. Someone else here has also done it but did another method. As for what RPM to set it at, it doesn't matter as it will hold it from idle to redline. If it's an N/A motor you'll want around 35-38* , if it's turbo 18-30* depending on boost, turbo, fuel ect. I ran 22*. Quote Link to comment Share on other sites More sharing options...
