What's my car worth?

Car had 0 rust to begin with, just the stock unibody is a turn off to me as even a stock 340 can twist the body slightly, it is an awful frame design. If im going to do it right, do it properly and to the 9's

That's just your opinion, and you ask whats the car worth, not weather or not you can build a better frame. You did a lot of work to fix something that wasn't broken. Now that's just MY opinion. And there were leaf spring unibody cars running in the 9s back when these cars were new, just sayin.
