I would rather spend far less money and get this:
-8.4L V10 = 600hp / 560tq
-Updated T-56 Tremec
-Twin disc clutch
-Variable Valve Timing (crazy sophistication for the Viper)
-Electronically actuated throttle (more of that crazy sophistication . . .)
double the horsepower of the "cheapest supercar" and $20k left for forced induction goodies
