It really is a bit of a shock how weight can vary from one Fox to another. It all comes down to options and body style and year. The difference in weight between a fully loaded '93 GT vert and a no option '79-85 coupe can easily be as much as 500 pounds. When you start throwing on 17 inch wheels and huge tires, superchargers, nitrous kits, roll cages, subs and amps etc, you can easily build a car that weighs 3500+ pounds even with aluminum heads. Then again, build a coupe with light weight wheels like Draglites, throw in a tubular K member and A arms, get aluminum control arms, rip out the sound deadening and trunk panels, swap in a fuel cell, built a stout carbed engine aluminum heads and with no AC and manual steering, get a pin on fiberglass hood (usually lighter than the bolt on kind), swap out the steel bumpers for the older aluminum versions, get light weight racing seats, rip out the stereo..etc, and you can easily build a car that weighs a scant 2600 pounds.
Sure, with enough power anything can be fast....take the Terminator Cobras and the GT500 as good examples. They're pigs but with their blown engines and awesome brakes, you can get away with that. Then again, that same 500hp in a 2600lb car is going to be a LOT faster. Power to weight ratios are really fascinating IMO. The lighter you make a car, the less power you need to be as fast as the next guy and everything from accelerating to braking to cornering and even mpg will improve with less weight.
