Diagnosing a miss

I am trying to diagnose a misfire on my 71 with SBC. But, I cannot figure out where to plug in my scan tool. Any ideas.....

I decided to go old school and held a piece of cardboard over each tailpipe to try to determine side to side, but couldn't tell. Finally figured out it was number 8 wire burning and shorting to the exhaust manifold. You can see the sparks even in daylight....
