Power seems weak, but this is an old car with a lot of miles. The car I'd also an automatic.
the distributor is new, the wires and plugs as well.

Will i see a big FE Improvement by fixing the issue ?
What is the condition of the ground wire on the cylinder head. You can a simple test by taking some jumper cables and making four extra temporary grounds then recheck spark.
