I have a 340, stock bore, 10.5 pistons with Edelbrock performer aluminum heads, a mild cam, stock distributer, and master blaster coil. What gap should I run on the Champion RC12YC plugs? Out of the box, they range from about .30 to .35.

I run them at .045 with a high output coil , increasing the gap more just hurts the wires .
