Have you run the PHS docs? anything special about the car? You mentioned small stripes down the side of the car, is it an HO?
Post some pics so we can see the progress.
The direction you take with your car is yours to figure out. Which way are you going, stock, modified, custom, etc?
That's what drives what to do with it.
I personally like stock, especially if it's numbers matching. There are many ways to get some power and performance above what came from the factory and still have it look factory. Since you are going with a frame off, that will solve a lot of potential issues anyway (body bushings, suspension rubber, metal lines, rubber lines, new shocks, tires). Use the FAQ and search tools here. There is a plethera of information.
