Setting the dwell is a pain and I will be looking up a Pertronix very soon.
In the trip to the gym and back it ran OK, but I didn't push it and on the way back at over 3200 RPMs I sensed it missing a little.

Could this be arcing in the old spark plug cables? so it that I need to replace the plugs and go to a wider gap? I was not having these issues before the new MSD and coil so I am trying to work my way through the system.

I am running the old coil since the MSD fried and I have not received the replacement yet.

Any thoughts?

Something is amiss....you should able to set the dwell well above the factor spec.

Not that you should.

Follow John's advice! It's logical based on your statement:
"I was not having these issues before the new MSD and coil"

For more of an update and the ultimate resolution (hint, change your plug wires and suspect the coil). Check out this other thread I started later in the saga:

Intermittent misses - MSD? Distributor? Plugs?
