Re: [Chevelle-list] Detonation question

[Rollerclutch]

Maybe try 10 initial + 15 centrifugal and leave the vacuum advance connected and see what happens. You said you have the lightest springs in the kit?
 Keep experimenting. I like 10 deg initial because of the snappy throttle response I get around town, but you gotta fix that detonation at WOT cause thats hell on pistons and valves. Keep tweakin it!
