Mine is getting about 8-9 mpg also but I know its not running right.
I have a timing light on the way and a new distributor.
I put a new edelbrock 600 cfm carb on it, new fuel pump and new plugs and it made no difference on mpg but runs alot better.
I will see this weekend if the new distributor and timing helps.
Oh, mine is an 83 K10 short bed, standard gearing but I have a 4 speed manual with granny gear.
I get that mileage at 65 mph with AC on.
