Im pretty good about not leaving ignition on, but I specifically bought the Pertronx 2 because supposedly is immune to the ignition being left on.
On a stock street engine at whats a good RPM to have the advance fully kicked in?
(1) I wouldn't think the 2 or 3 are immune but check with Scratchn, he knows the ins & outs of em (2) set the initial with the vac gausge method/shorten the slots so you get 35 total & this is initial+slots with can capped) With this being a DD no hot rodding then plug the can in & likely just subbing in a weak spring for the OE thick one with the elongated end will sufffice. bottom line NO pinging wanted/allowed but for max torque/mileage you want to be pretty close to that (pinging) line. EDIT if you are going to romp on that 318 then slightly different procedure: after initial/total are set then mix/match springs so you are just under the pinging point at WOT up thru the gears on your hottest/driest day then plug in/adj the can. You definitely need a strip kit for the 1406
