Thread: Timing v8 3.5

Pinging is a loud clattering noise under load that might be masked by an overly loud exhaust. On gas its unlikely a standard compression 3.5 will ping unless badly carboned up. I suggest you use a timing light to check your advance is working properly at revs, sometimes the mechanism seizes and the only way for the engine to perform well is for adjusting massive static advance. Also check the vacuum advance. With a normally working dissy advance you should be able to run 6 to 12 degrees BTDC at idle no probs.

I was running mine on petrol at 6 degrees for a long time, since that's what the manual said. Then I started advancing it a little at a time and was surprised by what a difference it made. I'm at about 12 degrees now.
