Timing for start up

If the fuel delivery system is stock and dry like new, it'll take a bit of cranking anyway.
Years ago I was told "just set the advance servo about square with the engine and it will run". Fine tuning is done later.

an 18 time nhra national record holder, and the best chevy mech I know, told me to put them on 30 degrees before tdc, drop it in on # 1 and go for it. worked on them so far---------bob
