If it was me I would put in 4:10's if your looking for more power with larger tires that is, I know my Silverado with 3:73's felt alot slower when I installed my 285's. But then you would be over budget since you have to regear 2 axles, but im sure your tranny will thank you with the 315's. Headers are nice but IMO dont help gas mileage eather but there are alot of options for that truck. With a Cam your MPG's will drop not improve eather and you cant go too serious with the computer anyways. IMO you cant have better MPG and more horsepower, because when you have more horsepower you generally dont keep your foot out of it and usally only end up with 1-2 mpg diffrence anyways, 350's arnt known for their MPG's. To get more power and better MPG's is why exactly I put a 5.3 in my 92' c1500 instead of a 350.
