Tuneup, check timing and tire pressure. Change fluids. And suck it up, because it still wont get great gas mileage.

Re: Need some help here.
expect 10-12 mpg empty with a tailwind.
expect less than 8 hauling loads or hauling a** 74 should have HEI, so make sure you do a basic tuneup. if you want to increase mileage and performance, your first modification should be the exhaust system.
