I have not tried a standard light but the motor runs like crapt above 1600rpms. If it is just the light, then it will still run like crapt above 1600rpms even with anoter light. This is why I think that the timing is advancing too much causing it to run like this. My hight idle (1400rpms) was showing 60 degrees so I am guessing that it is in the low-mid 60's at 1600rpms.

I will try and track down a standard light to rule that out.


What if there is enough differences between the FBO box and the MSD box and the 54 degrees that I am seeing is actually correct? I did not move the distributor during this swap and I assumed that I would not have to just in a box swap. What if I am wrong about that?

You did talk me into swapping the wires and I am glad that you did. I think that I had the wires wrong on the new connector that I added and I had electrical tape covering them so I did not see it before today. I will check my alternator wires.

Thank you both.
