Why not just try it and find out? The theory sounds about the same as indexing your plugs to get the electrode to face the fuel charge for better ignition. Is it better for performance? Probably, when you're trying to squeeze the last possible bit of power out of the engine. Will you notice it on your basically stock truck? Probably not, but if it doesn't hurt anything, you just learned a valuable lesson, and...best of all....you get to spend more time with your Bronco. Now that's living!
