bad engine miss?

Run the car in the dark with the hood open,see if there,s any spark jumping from your plug wires?I once had this problem on #5,7 cylinders on a 340.I now use boot covers with no problems.Just a thought..

Good call, I was about to suggest the same thing.

If you don't find anything there head back to the basics. Parts that "look" good may not be good enough.
