318 Engine stumble

What I decided to do was go with a skip white distributor. The gm hei version. I’ll start with that and then see what I can do with the timing to get it optimal

I also picked up a tachometer. I was using the actron, which is limited to 2000rpm. Can’t get total timing with that.

Should be able to adjust the mechanical with springs and vacuum advance curve with this. Will get rid of the coil, electronic box, and the ballast resistor. I’ll get a total timing of 34° @3000
And get as high a base timing as I can.

Set the plug gap to .045 and go from there.

Will go through your check list in order as well.
