How does someone now what the right combo is, say if you wanted to build a 440 like Blue is that really rocks and you have an idea of the combo of parts you want to use, what formula do you use to determine what to use to get the final result. Say you want to turn 11.00's or better and you have all the right drivetrian components, do I pick a cam and base everything else around it? Is there a formula? How did you come up with that combo Blue?
