What MSD box?

Alan do you have solid core spark plug wires? Because if you do get rid of them as they will cause RF interference with the MSD box. This will cause a misfire that sounds like you are on a two-step. This condition is worse if the MSD box is mounted close to the dist.Hope this helps you out as I learned this the hard way about 20 years ago. Use suppression core wires ONLY with MSD ignitions. ( don't forget the coil wire too).

Try unplugging your tach. That happened to me once. It may be worth a try.
