Colder plugs?
Here's one of the Autolite 65 copper plugs I've been running since January. It gets run hard on whatever crap fuel the nearest station has, with an occasional bottle of seafoam or VP additive. Stock compression 360. Mild cam, iron heads, RPM intake, Quick Fuel 600 carb,headers and hei with 36° total. Engine coolant stays in the 185 range and it pulls 18" vacuum at 700rpm idle. What are your suggestions? Colder plugs, more carb or timing adjustments or just run it?
