Engine misses when driving, has plenty of power and otherwise runs smooth. I have replaced fuel pump, filter, ignition switch, plugs, wires, rotor and distributor cap along with the coil. Have added heet to gas thinking it might have water in it.

Good morning,

Did you check the compression?

Due to the age, I would also inspect the valve train to be sure nothing is worn out.
