I've got an 84 too, except it's a crew cab. But same drive train and suspension, so it shouldn't be that much heavier.
Without any tools or people in it and about 3/4 full of fuel, it weighed about 7600. With me and tools and superfluous crap it's right at 8000. That's also including a fiberglass canopy; if the canopy is gone, the 5er hitch goes in it's place and weighs just about the same amount.
In comparison, my crew cab is over 1000 pounds heavier than Fordguy100's standard cab, which doesn't sound right.
