I know the inline pages, but since not registered I have to ask here. I am one of about half a dozen guys responsible for maintaining our sweepstakes prize 66HT with 200 and automagic.
Factory settings: 12 degree. The engine shaked badly off idle, we raised the initial advance to 25 where it pinged a little, then backed off slightly to 23. No shakes, no pinging. The manual says that mgp and performance might improve with extra 5 degrees over 12.
The head has been milled because of warping, so compression has increased. It either shakes or pings with 87 or 91 (US measurement) oct but gives a few degrees of freedom with 93.
It had distributor with both centrifugal and vacuum advance. The vacuum didn't advance much. Now it has vacuum only advance distributor. Should the vacuum advance conncetion be in the intake manifold vacuum or in the ported vacuum?
