Timing was set with vac line plugged to 34. The side elec read shows more than that since it is clean further 1/2 way down the base of the side elec. Everything is hooked up properly for vac, valve cover to rear vac line and front vac line to dizzy. We are jetting down since carb came with 76/86 and 35 idle feeds. The new carb is a 4150 dp, flowed to 780cfm true since I will be changing the heads soon. Ray in all seriousness, I couldn't hear pinging in this thing with good ears. Plugs don't show any signs of detonation though.
By way let me thank you again for the great mirrors.

FMS says not to go over 16 initial but the more I search I think they are wrong. Biggest issue is I have a duralight set up with FMS/MSD ignition box. Only way I can dial more initial into it is to find someone with the vanishing distributor machine. I must be old since I remember when all the shops had them. I am looking at the Crane set up since it will also handle vac advance initial/total adj with simple screw adjustments. Knowing what I know now I would go straight mechanical but carb builder says I can't retro the carb. Must be more than just plugging the vacuum inlet/outlets.

Thanks
Jack
