i dont think you'd need more than 300 to stick it up with the big ol v8's at the strip....
those v8's sometimes weigh upwards of 4k lbs.... well more than your 2 in change.
i find 90% of the people who start out with your intentions never make it there. let alone ever start.
set a goal of 250 or somthing more realistic right now, then slowly build up.
