Being a professional tech for 30+ years and reading many of David Vizard writings he has my utmost respect. Is he always correct? maybe not. But how many of us have the experience and abilities that he does. I have been reading his articles for years and have learned a lot by thinking "what if ?" Have You? I thought so. Ask any of the regular posters, Pro Power , CNC Blocks, Big Joe1, Mike Jones. Did everything they tried work, probably not? Let me say this, If he hadn't tried it would you have? BTW who makes the best BBQ? It's kind of the same thing tomato or mustard? Is your short rod motor beating my long rod motor because of the rods or the cam or heads or headers or gear or chassis or carb boosters or ignition or ? All I'm saying is respect the man for what he's done and published. Ask your competitor how he beat you and see how much information you get.
Why is the least trained, lowest paid tech working on the most important part of your car, THE BRAKES ! I know I work next to him.
