This question has been bothering me since I got my first Ford. Unless you do a lot of work to them, which in IT is not legal, or in stock car racing is cost prohibitive, they are slow. I don't know about the muscle car era, I was too young. The Fox bodied Mustangs seem to go pretty good with a V-8, but again, that's not an IT car. They don't make much of a mark in Sprints, Midgets, or dirt late models. Forget sportsman drag-racing. They almost totally suck in WRC. Totally forget World Challenge. In NASCAR, the politics are totally wrong at the present time. What is the problem? They are too heavy, they don't handle, they never have any brakes, and they don't have enough power to get out of their own way. Why? I would rather push a Ford than drive anthing else, but if the parking brake is stuck, Im leaving! Whenever there is a Ford that runs, the parts or even the whole car is not available to the general public. That is just so wrong!!!
