Compression ?????????

I'm not sure what kinds of cars you were previously interested in, or if you have any drag racing experience... But, it takes more than an intake, an over sized carb, and a cam to un a 340 in the 12s. 13s is fairly easy with basic nolt ons, mild to medium gearing, and a basically stock convertor. 12s needs a bit more of a commitment in terms of the whole package. What exactly is your budget on this, and what are you starting with?
