Pretty simple, unless things have changed over the years (got a REAL strong feeling they haven't). CUBIC DOLLARS! "Used to say at the Speed Shop, back in the day when there used to be speed shops, LOL. "How fast you wanna go, how much you got to spend"?
After spending all the money, "all you gots to do is tune both the motor AND the car".
Seriously, good luck. When I sought to get a car into the 10's, took alot of work and sweat and dollars. Parts are alot better today, bet it still takes a fair bit of sweat and work.
