thanks for the replies gents! hillclimb#42, that thought of electrode positioning is the real deal. i know race car teams have special washers(measured in thous.) that they use to get the positioning right. if your going to do it you want the electrode to face the intake side. the racers say that it helps achieve a more powerful detonation which gives a slight power increase. thanks again guys, im off for st. anthony's Idaho. ill let yall know how tha trip went when i get back home. a k5, a paddle tire, and dunes, doesn't get much better than that right.
