Hi Guys. Anyone have experience with setting ignition timing? 318 two barrel auto in a 69 barracuda coupe. Previous owner said to use premium gas to prevent knocking. Thought that strange advice for this type of engine,but. When we got home after 700 miles, tried a timing light and got 2 degrees retarded. Emission sticker says zero degrees adv.Now running 8 degrees. Anyone got experience on setting for regular grade? Don't know if I could hear a knock if it was set too far adv....thanks.
