I heard that if you have a higher powered or non-stock ignition such as the msd 6al and coil that i have, you can increase the spark plug gap over what it would normally be to get a better/more complete combustion without getting the misses that you would normally get if you increased the spark plug gap? is this true?

 

For the most part I think thats true. But I dont see you gaining power in an LT1 by doing that.
