Gas mileage really sucks?
It sucks gas I know it's a 350 with full time four wheel drive but I should be getting more than 4 mpg

you can save serious gas mileage get a set of warn hubs so you can technically be running 2 wheel drive you can unlock and run too high also it's probably a good idea to tune up your engine spark plugs fuel filter oil change air filter PCV valve check your timing. It also might not be a bad idea if you have a full-length exhaust maybe not in good shape to possibly put a set of good free flowing headers on there. also rebuild your carburetor and make sure you have it dialed just right.. Also don't forget to change your cap and rotor
