Sorry my racing days are done, to get that kind of ponies a stock engine won't do it, they are just not built for that.

450 to 500 HP at the wheels will require a supercharger, dyno tuning and about $7,000 minimum. Then you can spend more money beefing up the transmission and possibly the rear end to take the power.
