What have you got for a transmission and rear end gears? If you are pushing through an automatic with low ratio gears you may getting about what you can expect. It seems a little low, but it is a big block gasser! Make sure you are tuned up properly, clean and properly gapped spark plugs, clean cap and rotor, good ignition wires, ignition timing set properly, distributor curve set properly, vacuum advance working properly, no leaky vacuum lines, etc. Being a '96 is it fuel injected? If not, make sure the carb is adjusted properly. There are many things that can lead to poor fuel economy.
