Just wanted to thank everyone for their input regarding this.

Next weekend I'm going to run some new wiring back to the battery for both the Positive and Negative connections. Also going to remove the MSD wiring running to the distributor from the common wire bundle that it's currently in.

Just to make sure, I'm going to reinstall the original carburators on the car to ensure that the new carbs are not contributing to the problem. I'm sure that they are not, as the condition is the same prior to swapping them out.

Also going to disconnect the alternator. An old friend of mine said he ran across that once with a MSD. The alternator was spiking and causing all kinds of problems with the MSD. Didn't find it until they hooked it up on a scope and seen the alternator issue. Even then they did not relate it to the misfire. But they changed out the alternator and the misfire went away.

Anyway, thanks again. Your help has been greatly appreciated.
