Hi there!
If you are looking to buy a new carb for the purpose of improved mpg, I would first consider one of these.

Its a self learning fuel injection system, that will get you the best fuel mileage because when cruising, its constantly trimming fuel to keep the engine running at stoich air fuel ratio. You mentioned that your truck is a long bed, is it a 1/2 or 3/4 ton? What rear axle ratio does it have?
