I'm probably underestimating the difference in value today, given that my engine alone is probably worth close to what your car is worth. LOL! But like I said nobody here has ever seen your car, if you even have one . You scrape up used crappy old parts and put them on your car and call it good. You call it "old school", I call it ratty. I like to put new, or rebuilt, reliable parts on mine and bring it to the highest level I can...that's what I enjoy doing. And the assembly is still actively underway. When finished, it would probably take at least 10 of your cars to buy it. If it was for sale.
You always talk about how "cheap" you built your car and your boat anchor huge rearends. That doesn't impress me at all. What you did to yours is irrelevant to this thread, imo. Not everyone has parts laying around, and not everyone wants a car that drives like a 70's car. The OP here was looking for information as to how to upgrade his car to pro-touring, not how to put together an old-school stock height rat rod....with a carburetor!
