I have a very old H.E.I. dist. that I have used on alot of my engines for a long time. I recently built a high performance 350 and used this same dist. again. Can it put out lower than original voltage resulting in a weak spark and not a good burn in the combustion chamber without actually going out all togeather.

Yes it is possible. One thing that can happen is the coil develops a crack allowing high voltage to leap out of the coil case to the coil core or other nearby component. You might inspect the coil for a white film in a spot near a pin hole or crack. But if the crack is between the coil form and the core you won't be able to see it. I suppose it is possible that the ignition module itself could lead to a weak spark condition.
