Couple questions
So I'm looking at getting a 1987 F250 4x4 it has a 460 w/ a 5 speed transmission I know it's not gonna get the best gas mileage but I'm wondering if any one knows what it should get from what I can tell it's all stock haven't looked under it or driven it yet since I don't have the money for it atm.

ok any tips aside from a bigger exhaust and better headers to help increase mileage a little? and as for the tires right now it has 245/60 R16's on it I was thinking about going a little wider but not much maybe a 265?

245 to 265 wont be any different in mileage. even up to 33's still wont change much, just have to calibrate the speedo.
as for increasing mileage, it depends on how bad you want it, and how extensive your skills are. cam swap and ported/milled heads will help in power and mileage, and higher the compression the better your mileage will be.

ok any recommendations for a cam? I'm not gonna be hauling much and even when I do it won't be that much weight so I don't need a big power boost

My 96 F250 4X4 gets 8-9mpg if I drive it empty and VERY easy. But I have a C6 trans so no overdrive and 4.10 gears. So I get lousy gas mileage but got LOTS of power

Going wider on tires will likely hurt mileage as it will have more wind drag and probably more rolling resistance. But a 265 (10.5" wide) isn't that much more than the stock 235 (9.25") so the difference might not be noticeable.

Not sure the gearing in the one I'm looking at but it has a manual transmission so it should help with gas mileage a little maybe later on ill put an EFI engine in it

245/60-16s are tiny tires for an F-250, only 27.5" tall. Stock size is 235/85-16 which is 31.7" tall. If you really have little tires like that you might actually get better mileage if you put taller tires on it, because you'd be slowing the engine down almost as much as shifting into overdrive.

the tires will all be replaced regardless so size isn't an issue trying to decide if I should go with a 17" since I'm sure there are more tire choices in that wheel size. but still what would be a good cam for the truck. and I might port and polish the head as well but as I said it's a work truck so I haven't decided yet

This is a cam that works well with factory speed density and is very torque friendly. The lift numbers are with 1.6 rockers, 1.7s would net a noticeable difference with full exhaust. Valve springs recommended.
