Uh Dad...........You don't have to ask Phil anything for approval. As we have told you numerous times.....the "National Rules" that were agreed on involved members from five central United States Lightning Sprint groups. Not just Mark and I. This is about the 3rd or 4th time you have reminded me about the naturally aspirated clause in the rules. The rules update this winter will address that. Fortunately, you are the only one with an issue about this......everyone else knows the intent. I would imagine if you came rolling into a race with a turbo'd or force induction motor, I wouldn't be the only one pitchin' a hiss fit.
