Here's a picture of my "bone stock suspension" 1977 F-150 4X4 which was taken a week after I purchased it in 1986 with then 35,000 miles, 351/auto. I still have it. I have leveled the picture so the tires are at same height, shows stock rake. Tires are 31/10-50-15 which are pretty darn close to same height as the original tires.
The lift blocks between the rear axle and springs are stock.
I tell you all that so you know how it's equipped as to anything that might affect ride height .... you can compare it to your's in height and judge.
As to your question.
I got a better road feel and much improved steering by removing the original steering linkage which consisted of the inverted "Y" tie rod set up and pittman arm and replaced the whole setup with the 78-79 style tie rod / draglink / pittman arm. You need 5 pieces .... long tie rod end (rt) / short tie rod end (lt) / adjustment sleeve / drag link / pittman arm (differs too).
Compare three pics below to yours, and note that your stock '77 inverted Y changes toe in with every dip and bump. This 78-79 set up does not change toe as the tie rod is parallel and fixed with axle. Drag link parallels panhard or track arm as well so swings through near identicle arcs so no bump steer either.
Since those pics were taken in 2010, I have replaced the drag link itself (Moog) , it went 65,000 miles and the ball at the drag link was worn creating slop. The rest of the set up is still tight. I removed an added damper that is barely seen above and behind the drag link that youi might notice in the view of right frt, I just have the one in front on it now .... a 25 year old Moog that is still pretty stiff through travel.
You can also see some front sway bar brackets hanging down. I had spot welded with just a spot or two of weld when I installed frt and rr sway bars years ago recovered from a Bronco (big Bronco). I didn't like what they did in increasing chassis flex and removed them shortly afterwards. The brackets weren't spotted to the donor vehiccle, a U bolt wraps around the axle. I may reinstall rear sway bar. I just tell you all this as you may notice the brackets, but they are not original to the '77 F-150 truck.
The red bushings you see are also 25 year / 65,00 mile old red Polyurethane 14 piece 3 degree C-bushing kit. 3 degrees rotates the axle back increasing caster. 14 pieces includes radius arm bushings, C bushings, track arm bushings and sleeves as needed.
I also have gotten great service out of the NAPA brand HD GAS shocks which I think were actually Monroe Magnums with white paint and put in NAPA boxes .... good 20 year old set.
But the Poly bushings and 78-79 steering is my recomendadtion for you'r still stock '77 F-150.

The blocks on the rear are stock peices on any dent 1/2 ton. The pic showing the ride height on the truck looks like any other 1/2 ton dent 4x4 with springs that are not hammered................................No lift going on there. It's a stocker, with poly bushings and aftermarket shocks. If the tires in the pics are 31x10.50x15's, that may contribute to the illusion that it sits higher than others you have seen. The others would sit the same with the same tires. BTW, good lookin' truck............................

Thanks on the "good lookin' truck" comment though..... that was in 1986 when I first bought it. Might even go back to that paint iif I don't sell it first.
