1991 F150
I love my truck but need something to haul my horse (soon to be 2) around in Colorado (some foothills travel). I would prefer to keep it and just do some improvements. Can I make it the truck I need?
Here are the stats:
1991 F150, V8, 302, 5.0L, 4WD, exteneded cab, short bed, 5 sp manual.
PS I have the lightest wt 2 horse trailer on the market but the truck still struggles. I know I need stiffer springs and shocks. I just don't know if my truck can have a larger/stronger engine without having to change all the other parts.

A 5.8 is a bolt-in, a 4.9 is not...

I have a 92 F150 regular cab,short box,5.0 with 5sp,4x4, and it has 4.10 factory gears. It is rated to pull 5800 pounds.
The PO pulled a two horse trailer of 4000 pounds gross for 12 years here in Colorado without a problem. The truck has 108k miles on it and runs like a top and still has the original clutch.
The 4.10 gears are the solution to pulling with the 5.0.

Well, define "struggles". My '91 300 Six "struggles" up hills when pulling my QM trailer, but it's got the 3:08 gear and I like the mileage when it's unloaded. The truck still makes the hills, it's just slow. You are being told to put in the 4:10 gear on this truck and we still don't know what gear you have. The 4:10s will sure make it pull, but your MPG, what little you have, is going to take a dive towards 10, is that really what you want for this truck? How much time do you spend driving it with the trailer vs. without?

I had an 05 powerstroke for work and it had to work on hills with our loaded work trailer(10000-12000 lbs)----by this i mean i wasnt used to pullin a load so it seemed hard on the truck but probably didnt even phase it---i would only pull the trailer 2-3 times a month so if your pullin that little i wouldnt change the truck

Thanks everyone!
Lots to think about. I don't know what the gearing ratio is and not in a position to look (out of town).
I only drive the truck for horse stuff. I have a Yaris for daily stuff. The trailer weighs 2600 lbs so even with 2 horses it is still less then 5800 lbs as someone pointed out.
I get about 15 mpg without the trailer and too pitiful to calculate with, but that is to be expected. When I hit hills though the momentum cannot carry me and I end up going about 20-30 mph even on the seamingly little hills.
I will check out the gearing when I get home and someone else suggested checking the compression. Anything thing else I should check before putting money where I shouldn't?
Thanks again!
PS Would getting a gooseneck trailer instead of using my bumper pull help any? The weight would change to the axles instead of the bumper.
