Bostonian 71 demon

What drives the second head, gears or belt? Have fun phasing that contraption! I’ve only really seen the crossed dual distributors with the meshed shaft gears. What years were these types of dual distributors in use, like mid-‘70s

Regardless, you got some cool parts for this thing. It’s pretty ambitious to find and use all this relatively rare 45-50-year old technology and try to make it run a number consistently. I can barely handle one distributor, two might make my brain fall out.
