Timing advice

Some great info here. This thread should go to the tech archive section. :thumblef:

I do not have much to add, except for a caution on using dial back timing lights with a multi-spark CD ignition box (like MSD). You will likely get false readings below 3000rpm. This is about where the ignition switches from multi-spark to single spark. MSD recommends using a non-adjustable timing light.
