How is it going,
I would check your engine, make sure it is tunned. Is the truck 2wd or 4wd. What size tire do you have on the rear? If you have a larger tire on the rear this is part of your problem. Well the real problem is your tranmission. I am a true blue ford dude, but the 3spd and 4ovd are the most worthless transmissions. The way too high geared 4spd overdrive combined with your high geared rear end equals no low end power.
You need to put in a c6, 4spd(borgwarner t18 or np 435). These tranmissions don't have a overdrive gear but are much more suited for 0 to 60 mph. With particular instrust on the t18 and np435 because the have a granny low first gear which makes all the difference. I had a 3spd (same as yours with no od) in one of my 80's 2wd 6 cyc, and got struck on wet grass on a hill. NO mud mind you just wet grass.
Good luck,
ITS all in the gears.

if it was my truck, i'd switch the rear to 3.08s, and put in a t-18/t-19
the granny gear will let you pull like crazy, and the 308s will keep your motor into the powerband when you are cruising.

I had a 3speed stick w/ od, and 3.55 gears (had a 6 with clifford intake/headers,44bl), and it ran good, but it just didn't have any thing over 3500rpms (it'd pull, but just for the fact it was geared and wound up with a big carb). plus the OD tranny was the biggest piece of junk i've ever used.
do you still have 235's on your bronco or 31x10.50s?

My 300 averaged 18 MPG loaded, over 2100 miles... 290H cam, headers, 9.1:1 compression, and, the good 'ol 1bbl, NP 435 and 2.75 gears with 31x10.50's... Best I did unloaded was 26(441 miles on a 17 gallon tank) It LOVED to criuse at 1900 RPM, and 100 MPH was a mere 3000 RPM....

The 2.45 gears are your problem. I had the same gears and i ended roasting the tranny clutch and flywheel(the flywheel looked like a dry lakebed it was so cracked) To solve your problem you have to tell me if you want to keep your od tranny or not. If you do get a set of 3.55 gears and a new clutch (does your truck chatter/vibrate really bad at takeoff?) due to the gears and maybe a flywheel if its cracked really bad.
As for what i did to fix my problem i went with a toploader 4sp wide ratio tranny (bolted right in) the clutch and flywheel that came with it and a set of 3:1 gears. I recomend this combo because the gearing is just right but if you want some more grunt with this setup get some 3.55 or 3.73 gears.
