I'm thinking it's the fuel too, and so does my friend Rick who helped me build the engine. Damn. Premium is about $2.50/gallon and by summer it’s bound to be higher.   John Nasta       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of [EMAIL PROTECTED] Sent: Sunday, May 01, 2005 8:47 PM To: Chevelle-list@chevelles.net Subject: Re: [Chevelle-list] vacuum advance hits manifold   TO get rid of the ping, you need to retard the timing a tad, try about 4 degrees and give yourself about 32-34 degrees of total timing.  Running a higher grade fuel will also help eliminate a pinging problem.   Tom
