I have a 92 ext cab short bed 350 tbi 5spd 373 gears. I have replaced plugs wires rotor and cap throttle body and electrical with a 1" spacer and it still bogs down when I get up to hwy speeds it does great in town unless I get into it its a project in the making but its my only means of transportation..... Please help....
I am also wanting to lower it how much drop will I get if I "flip" the rear end and I know its not the best way to do it but how much of the coils should I cut for the front to still be lower than the back after I flip the rear

A flip will = a 6" drop. You can go to 7" or 8" with a lowering shackle, but then you'll have to adjust the pinion angle with a wedge.
You will also have to notch the box crossmember right above the rear end pumpkin.
Cutting coils = 2" for every one removed.
Best bet to drop the front 4" is a dropped spindle & one coil cut.
There are 2 major manufacturers of dropped spindles. DJM & Belltech.
The Belltechs move the wheel out about 1". This is because they were originally designed when a 17" wheel was considered big and without that 1" of outward push, the wheels would hit the lower control arm. DJM's do not do this. But even with those, anything smaller than a 17" wheel will require some grindage to the gutters on the LCA. Both front & rear sides of the LCA will need to have that done.
I have pix of that if you want.
Get the stick-on style of balancing weights when you get the wheels balanced. When lowered, the lower control arms have a tendancy to rip the clip-on style weights off of the wheels.
You can get 2" dropped springs, but they mimic the original ride qualities. Which is to say, kinda soft & mooshy. Cutting coils increases the spring rate & creates more of a performance feel to the suspension.

Also, it's probably a good idea to relocate the rear upper shock mounts. The 6" drop puts them at an almost useless angle.

Worried about lowering his truck when it doesnt even run right. Sounds like me when I was in high school LOL!

If you have messed with your timing, I would get a timing light and have someone set it properly. Also, your fuel filter can be partially plugged, I had an 89 that did this same thing, new fuel filter and I was good to go.
