v-6 in early A-body

Thank you for the post of those pictures, they help me in many ways. I see the way the tone ring is situated just past the gear teeth. The V8 spacing is about 45 degrees because of the 8 square holes. Not sure the exact edges used for trigger (inside or outsides of holes), but it gives the timing window for subdivision used by the ECU timing control.

I am with you, use the magnum ECU and sensors, for simple unstall.
