Just to play devil's advocate...... If you haven't owned a car for a long time, and you don't have a lot mechanical skills, then IMHO it is too tall of an order to become all that familiar with your car before doing any mods. You might be years before doing anything.

You're absolutely right, it might be years. But that's better than years of chasing a gremlin that doesn't exist, throwing money at something that doesn't need it. OP wants a 12 second street car. Not a really tall order these days. And his car might have it in it already, just needs a few low dollar tweeks. He might love his gears, but maybe that's what's holding him back. Or converter. Or cam. Can't know until we know what's in there. And if he want's 12 seconds, he might have to give up those gears he loves so much. In the end, he has to pick and choose what he wants. Sacrificing those gears so he can reach his mid-low 12's goal. But it can be hard to choose when you aren't sure what you're working with.

I just hate to see guys follow the old "well you need heads" "oh i ran this cam and it was great" "I'd change that carb" advice, when in the end it's all about how the entire combo works together. There is no magic key or magic part, that will suddenly help you hit your goal.
