You know, these cars are low. In fact, it's one of my biggest bitches about the lack of ground clearance on my '71 Mach 1. I have not lowered my car, it has the heavier front and rear springs that come on the 429 cars that I had installed on my 351c car, to help with towing loads, so it should even be a bit higher maybe, but it's not. I tow with my car, and if you've ever backed up over the crest of a launch ramp you'd know there are times that you can scrape in the middle. I've always thought that headers would be a no-brainer as far as horsepower bolt-ons, but I crushed a brand new set of headers after only having them on for one week, when I went to the grocery store and drove over a speed bump in the parking lot. Goodbye $$$$$. If you stand next to the car and put your arm straight out, your arm is nowhere near the roofline. Overall, my stock suspensioned car is as low as a good friends lowered '69 Mustang.
