Best next upgrade?

I'll drive it to work a couple of times a month when the weather's nice.
"Spirited" Sunday drives on back country roads, occasional car meet up. It's not pretty enough for a show.
Will probably take it to Woodburn drag strip once or twice in its life just to experience it.
I'd like it to be safe, quick and cool, probably in that order :p
Take it to the Mopar Nationals and enter the sportsman class. Usually a 16 or 17 second car wins that just on consistency alone..
Nothing like bringing home a trophy from the Mopar Nationals.. of course the car show and swap meet as well while you're there...
Usually sometime in July...
