7.3 or 5.9

[diesel17]

I need alittle help on deciding what to get 7.3 4x4 manual f350 or a 5.9 2500 4x4 manual. I am mainly looking for best mpg which i know the 5.9 has but i rather buy a ford if i can get the same. I was wondering if i put like a 3.05 gears if the ford would get the same or better milage. Thanks for your input!

I get 18mpg everyday driving, 24 on the highway cruising. The F350 most likely has 4.10:1 gears. I would not go so low to a 3.05:1 gear ratio. In fact I would not go below a 3.73:1. My truck has 3.73:1

but isnt it the lower you go the better milage you get?

And by the way thats a bad *** buck man congrats!

Lower numerically gains mileage. Like 3.73's get better mileage than 4.10's. It's a ratio thing. 4.10 revolutions of driveshaft to one turn of axle. Engine turns more times to go the same distance so more fuel is used.

so there is deffinatly a way to get just as much milage as a 5.9. cause i honestly would rather have a ford i ve been a ford man since i got into cars and trucks

Same mileage yes, but same setup probably not. Equally set up trucks (same cab config, bed length, 4x4 or 2x4, and gear ratios) the cummins will get better mpg almost every time. My 01 7.3 averages 16, my dad's 99 5.9 averages 19. Fords are heavier also which hurts their mileage.

What buck? Anyways, yes you could get mileage out of a 5.9L but you keep saying you want a Ford. Ford does not have the 5.9L.

yeah thats what i kinda figured i thought they were more heavy. have you had any problems with your 7.3 so far?

[diesel17]

yeah i know i would have to buy the dodge. and there was a buck in your pictures
