1986 la 360

It has vacuum advance. I unplugged it at the dizzy before adjusting the timing. I cough a glimpse of it in this photo. I highly doubt it disproves it being a lean burn dizzy as this is a cali truck. Where would the ecu be mounted? It's not inside the fenders. Also, what re-writing needs to be done? Perhaps I only THOUGHT hei swap would be a walk in the park.
