He said as soon as he did that, many racers would be buying new roller profile cams, and would open a whole cost to the sport. I think those who are waiting for the rule to change should come up with another plan, whatever that may be.

That makes absolutely no sense , if the facts are as you are saying, he is flat wrong about the cost, he should check his facts before making a statement like, it would open up a whole new cost to the sport ,in many cases the older cars are already buying the same billet cam ground for a flat tappet cam ,and having to use tool steel lifters that cost way more than roller lifters in many cases.
