Thank you very much guys for all of your help!!!! I got the beast running once again. It was the **** crank position sensor. Just a quick question.... After replacing the sensor the tach gets to about 2100 rpm and starts to flutter. It is also tough to get it into overdrive but once I let off, will go into overdrive. I set the gap at .50 with a brass feeler gauge. Am I dealing with a tolerance issue or a dirty harmonic balancer causing a deflection? Thank you all for the helpful advise.

The usual cause of fluctuation is a loose connector in the wiring harness up behind the thermostat housing above the alternator. Follow the lead from the Engine Speed Sensor up to where it connects and then pull it apart and clean that connector.

I also use a matchbook cover as my feeler gauge for setting the engine speed sensor. I have found it works better than the feeler gauge. Just roll the engine over and make sure there is no interferrence with the sensor and the damper, and set it so it clears the closest spot by at least one thickness of matchbook cover. The damper is two chunks of metal, one outside of the other and bonded with a thermorubber compound between the two. It will take a slight offset over time, and you have to compensate for that.

I also vote for a poor connection.
Pull the connector apart and slightly smash the female ends with pliers.
