I have a 2002 426 that I have just purchased a used Dr. D pipe for. Being the power nut that I am and reading what I have in these posts, I thought this might be a good time to start messing with the carb and jetting to squeeze a little more out of the old girl. Here are the questions that I have: 1. Is the "BK Mod" necessary and helpful for the 2002 model? I have heard mixed opinions. 2. Should I build one of those fuel valve gizmos? 3. I live in Dallas. Anyone that has had success with a similar arrangement that can contribute carb settings would be cool in my book. Thanks.
