The 3.0 is slow for many reasons, one is that misengineered and very restrictive crossover, the other is the air intake. The biggest problem w/the 3.0 is that it can't breathe, it's congested! Let the engine breathe by getting rid of that restrictive x-over, put some headers on and modify your air intake and she runs pretty well! <img src="/forums/images/graemlins/kewl.gif" alt="" />
