Plug readers
Ok, here’s a couple of plugs after a 50 mile cruise yesterday. No WOT runs. I have added vacuum advance FBO billet distributor with 20* initial, 14* mechanical @3200rpm, and 12*@12” of vacuum per Dons recommendation. I think I’m really close here. What do the gurus think. 2 plugs here with 2 different heat ranges.
