I have an 8" Coan behind my 434, it works very well, great folks to work with too. When I was calling around shopping for converters Coan asked more questions about my car and what I was doing with it, then made their suggestion.
As mild as the OP's combo is I don't think 3000-3200 is out of line, he could always ask if they can make it 33-3500. I'd call and talk with them about it.
