It can stand a good bit more initial timing, but you will probably need to end up limiting total mechanical timing somehow. My stone stock 351M in my 75 F250 for example is at 20* initial and 35 total.
Oh I totally agree! This dizzy has a wild advance in it, so I have to run 8* or less in order for the total to remain within a reasonable area and not ping the engine to death. :burnout:
It actually started, idled and free-revved best at around 15-17*.
@Magiver, The carb is not always giving the engine 850cfm worth of fuel/air. The carb was $10, so hardly was it a waste! :)
