there is only one logic with me.... give the car what it wants. Once all people were taught the earth was flat..... if everyone is saying it, it must be true? All computer calculators and magazines think a 600 cfm is the best choice for my car. I started with a 600, and I believe i'm on my 4th carb and it has gone the quickest with the 750 dp. Now how many, even on this sight would have tried? Not very many. And they'd still have a 14 second car....
