SE Wisconsin Engine Builder?

The only shop that I'm aware of that speaks fluent Mopar is Kilpatrick's in Waukasha. I haven't heard anything bad about him and he seems to know his stuff. Is there anyone else in the region that can be trusted for the machine work, head porting, and maybe assembly for a 450+-ish HP 340 small block? I'd be willing to drive a couple hours for the right shop but closer is better.
