Dog tired or Dog aZ lazy?

[Acute Cut]

Bought a 1990 F-150 the other day. It is 10 times better than my Chevy. Granted it is 17 years newer too, hehe. I love the truck. It only has 79,978 miles on it. Can you imagine?

Anyways, i love the truck. It drives well when under NO load or anything. I have ZERO complaints about that. When i drive around town with my trailer hitched up it does fine, but when on the free way i am fighting to get above 55 or so.

I have changed everything i can think of to date. New fuses, oils, filters, gaskets, screens, and so forth. Granted, i have NOT changed the wires and plugs yet, but was waiting for more $$$ to fall my way.

Any tips or thoughts on this?

Just kidding. Is it gas or diesel?

gas. And congrats Kirby on the name change. Or should we even call you kirby still? hehe

Sounds like a 302 with wrong final gear ratio or too big of tires.

Is it all stock? 4x4? lift kit? anything like that?
