I'm not sure I'd start with what you're starting with, but I applaud the fact that you intend to take something and make it better according to what you want. That's how most of us learned to be hot rodders, by doing and learning from our mistakes. I left quite a few hulks sitting out behind the shed before I understood how things worked. Tear into it, do what you want to. If it works out, great. If not, try something different next time.
