Classic Mustang - Hi-performance coils in stock application

Anybody have pros/cons about using a high-performance coil in an otherwise
stock application (e.g., points, that sort of thing)?

It will provide a more powerful spark at the plugs with no detrimental effects to any other components. It does not change the voltage going to the points as that is determined by the resistor wire or ballast resistor. I believe the only difference is a hot coil has more windings which produces a hotter spark to the plugs. It's an inexpensive upgrade, easily installed, with benefits to both performance and fuel mileage.

This sounds like your distributor is installed incorrectly, perhaps off a tooth.

-----

would this cause it to over heat too???

-----

Also check your timing chain ... might be old, strecthed and have jumped a tooth or two from the backfires.

Check the firing order

Yes, it can. Bad timing causes all sorts of problems - exactly the ones you're describing. Put the #1 cylinder at TDC per the timing mark on the engine, then pop the top off the distributor. I'll bet you'll see the rotor pointing off to one side of where it should be.

Check your firing order you could easily have some wires on wrong plugs.
