6.8 MPG ok?

My 86 c10 is running basically a cast iron head ZZ4 rebuilt 750 quadrajet elderbrock performer inlet with ceramic long tube headers and a stainless 2.5 inch mandrel bent dual exhaust/700R4/ford 9 inch with 3.50 gears.
Sitting between 70-100mph(GPS NOT SPEEDO) on a recent 60 mile run with hard 3rd gear acceleration between those speeds on flat freeway I am getting 6.8mpg does that sound about right?
