are there any good indications of how to find optimum base (initial timing)? Most people say set it at 10-14 deg and forget it. Others say, set the max total advance you want and don’t worry about the base timing. I plan to recurve my distributor so this isn’t an issue (I.e. limit my mech adv once I know what base and max timing it wants). I’ve seen the articles showing to set base timing with a vacuum gauge, but when I do that, my base timing is over 30 deg! I guess I could set base lower and then add vac adv to get to that point? But base timing itself, that seems too high. I’ve also heard people (including msd) say keep adding base timing until the starter has a hard time with a hot engine and then back off a deg or two. I know I want as much base timing as the engine will tolerate. Just by going from 10 deg to 16 deg it runs cooler and is more responsive and doesn’t smell out the exhaust as much. Since the car is primarily a cruiser, base timing is more important to me than total timing. I’ve tried driving the car up a hill in 4th gear to listen for pinging, but my headers are loud and I hear the ticking from them. I’m still checking to see if I have an exhaust leak causing the ticking. I’m looking for methods on how to determine timing requirements, so the engine specs shouldnt matter. I’m not looking for a timing number to shoot for (if I was, I’d probably set it around 16 base and 36 total on a mild bbc) but rather a systematic method to determine I have the timing my particular engine wants with the gas I use at the altitude I live, etc, etc.... Appreciate any advice, thx!
