Everyone is going to continue to tell you different things cause humans all have different opinions. Natural to be over whelmed due to a thousand different directions you could go. Some times there is no black white right wrong definitive answer. Its fuzzy grey area at best and the right direction is depends, depends on a thousand things. To muddy waters further you say wanna flip wanna build dream car change interior to black tear car all apart buy used unknown carburetor and headers that prob wont fit etc. Then you done paid to much for car to ever be a successful flip etc etc. So now we are in deep muddy waters and what should one do no one knows....because these are all real hard decisions and depends on thousands of things etc etc etc....maybe let car sit in garage save money and noodle on it over time....one does not know....
