carb?
I would like to beef up a 302 in an f-150 not sure what year but I want to use a carb, the engine would have headers with 2.5exhaust, intake and a mild cam. I am wondering what kind and size of carb would be adequate for that combo and yet get good mpg, the carb preferably needs to be under $350. oh, and it will probably have a manual transmission.

I just recently got one for my Ranger's 5.0. Bought it second hand on Ebay. I took it apart, cleaned it out, changed the power valve (just in case) Put it back together and bolted it on. Works great. Motor is basically an Explorer 5.0 with a carb, same cam, but ported E7's instead of GT-40's. Sure could tell the difference between it and the 3310 750 it replaced. Like night and day.

What kind of mileage do you think I would get with the holley570cfm? I would like to get 12-15mpg but from what I've heard that isn't very likely, unless you have really low rearend gears and overdrive combined with a featherweight foot(whitch I DON'T have). Would the 570 be too much for just intake and headers/exhaust?

I can't tell you for sure what mine gets (my speedo turns backwards 
and is off a tad) but the one time I checked it it was close to 15 mpg. I've got 3.73's tires are 28" tall and no overdrive. The Explorer cam has a lot to do with it as well. Mileage usually depends most on your right foot.

Would the 570 work on a 351w with the same build? Could I get 12-15mpg with that set up? just asking because the 351w has more power(which I like), and I am finding some nice trucks with it.

intake-probably edelbrock performer, cam-mild don't know exactly what kind, headers-probaby heddman or flowtech full length. With dual exhaust and cherry bomb glasspacks, heads- stock until I can afford gt-40s, which won't be for a while.
