Rear end out of 79 trans am ( still not sure on the gears, need to open it up)

It drives fine. No leaks or smoke. Seems I have read these engines like running at higher rpms. Gas mileage is around 10 mpg, which is horrible.

Is this a good combo?
Is the mpg way out of wack?

Bring forth your opinions. I'm not a mechanic so all thoughts would be great.
