I read an article in RACER last summer about "Peterson White Lightning Racing" and how they switched from the 997 in 2006 to the 430 in 2007.

What they described as the real advantage was the better (ie. easier and more forgiving) handling of the 430. They believed straight line speed was about the same between the 2. I think the engine packages are comparable. It's the chassis that needs to be improved to be more competitive.
