Thanks for the help Larry !
OK, sounds pretty ideal. As long as it isn't pinging, and the plugs look good, and the car isn't surging at steady state high way speed, you're good to go. 34* might be safer for iron heads and pump gas. Look at the spark plugs. Sometimes you may not hear the beginnings of detonation, but you will see it on the plugs. Looks like little purple specs on the porcelain.
Ok, I will keep an eye on the plugs. If I wanted it down to 34, just add the bushing? And should I limit the vac. Adv. To 10 or 8,
No, simply reduce your initial timing to 12*. As long as the engine isn't surging, leave the vacuum advance as is.
Ok, thanks again !
