Bill,

You may be right. I don't know as it's NHRA's intention, but it can be made to work as they wish. So how do they know if a valve job is illegal. As Supreme Court Justice Potter Stewart (thank Jared) said with regard to pornography, "I can't describe it, but I know it when I see it". NHRA takes the same view on valve jobs.

Really! Bud's question has been up most of the day. Does anyone have a descriptive answer for him?
I don't.
