Change your cam, exhaust, and put on a supercharger. Should get you to enough HP to put a huge smile on your face for well under $10k.
If your 454mag has some hrs on it, just have it freshened up.
Either way, you can get the speed and acceleration you want for a lot more than $30k.
Also, don't forget to water test some props with your new souped-up engine...can make a big difference!
