I have a 1984 with a 351W, It was a california truck at one time and had that computer controled carb and dizzy, well I took out the computer and replaced the carb with a holly 4412 and a Hei dizzy my question is should I run a hotter plug now since I am running a HEI? Or should I stick with the stock ones?
2nd that, 'read' the plugs later to figure out if you need to change the heat range, but most likely you will not need to change the plug to a different type.
