what will it be???
I got a 1988 F250 4x4 that my dad gave me. the motor was blown and i am pretty mechanicaly inclined so im making it all carburated and putting some other stuff on it. im taking all the emissions crap off and the ac too. but i am saving it. so i am putting in a 351w and all im doing is getting a standard block and putting a holly 650 carb, edelbrock performer intake, and an rv cam. i am also putting 33x12.50x16 mickey thompson mtz tires and 16x10 micky thompson DC1 rims. with just the cam intake and carb done to the motor and 33 inch tires, what kind of gas mileage should i expect? it will have full exhaust with headers and true dual straights, and k and n air filter. so what should i expect?

without knowing what your "stock gears" are would be hard to quess mileage you will get.
look for the axle code on the door sticker.
a 351 with a c6 and modifications you want to do will be lucky to get 10 miles per gallon.
and if you have 3.55 or higher it may be less than that.
this does not count the hotrodding you will probably do.
