2.73? Is the truck your talking about the one in your sig? Those are to high of gears even if you have a 3 speed trans. I would just take your carb and boil it out good and make sure the float isn't getting to heavy and even lower the metering rods by a turn and see if that helps. Make sure the metering piston is free and doesn't bind. I have sanded it and the bore with 600 sandpaper and had good results doing it. You could probably go 2 sizes smaller on your main jets too if you can find some.
