Ok. Maybe I can try taking some out of the vacuum.     Brian Zack '70 Chevelle Malibu mailto:brianz@dpsabq.com   -----Original Message----- From: Dave Corgill [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 26, 2003 11:49 AM To: The Chevelle Mailing List Subject: RE: [Chevelle-list] Detonation question   At 12:18 PM 11/26/2003, you wrote: Where would you suggest taking it out of? Weights and springs? Vacuum advance? Or initial? Or a little out of each? Brian Zack '70 Chevelle Malibu mailto:[EMAIL PROTECTED] Vacuum don't count as total advance. When I read your post I thought you were adding vacuum advance to the mix because 48 is way to much. If it pings at light throttle take some out of vacuum . On my vortex head 383 max is 32 degs, 10 ini with 22 degs distributor, vacuum I use 10 deg pod. If you add it all up = 42. You need to ck the advance at 3500-4000 rpm with the vacuum plugged.
