how does a 318 engine run if timing is off ?

Ok, my friend was not able to come over, so before he left, he told me to pull the dist. cap and ohm the wires, and pull out the plugs so the next time he comes over we can do a compression test. So the next day I pulled the cap, checked the spark plug wires from the inside of the cap to the spark plug boot area, found 3 wires that had no readings, I was 100 % sure this was the problem since the last time we had the car running, my friend told me he thought it a few misses, so with 3 bad wires [ which was just poor connections at the dist. cap ends] , I reinstalled the cap and wires ran out of time so the next day I pulled the plugs to make sure they where as clean as possible till I could get some new MGK units. Anyway car fired wright up, BUT ran worse then ever!!!!, tried with jumper wire from + on coil to battery + no change.

So today I was able to track down some NGK plugs, checked the gap[.035], installed them , used jumper wire from coil to battery, I thought the car was going to blow up, it ran the worst it has ever!! pulled the plugs, they only a few seconds of run time on them, number 8 was coated with gas, some other plugs looked like they did not even fire, I have been chasing down the problem since March, I have replaced the dist. with a Pertronix unit with matching coil, replaced the Ignitor II module in the dist. BUT I REALLY FEEL THAT IT IS JUST A PIEICE OF JUNK!! seems like some times it is firing most cylinders and other times hardly any. All connections, triple checked,, all voltages are correct. all grounds are good.

After we do a compression test and make sure there is no issue in that area, I will remove this so called dist.

Has any one had good luck with a Duralast Gold Dist. from Auto Zone?, I will need to rewire the ignition system, since I do not have a resistor block, or module, or any plugs . I will need to get a correct coil , and control unit. wiring plugs to hook every thing up.
