Based on the recent timing discussion, I set the timing on my 68 289 (8.7:1 comp ratio, 91 octane) at 750 rpm, 15 Deg BTDC, which yields 37 Deg, all in at 2900 rpm. This is with the vac line disconnected. With it connected the result is: 800rpm, 17 BTDC, and about 55 Deg at 3000 rpm w/ no load. It drives fine w/ no pinging (glass packs make it hard to hear though). Sound right?
