The Suburbans were fuel injected from 1987-1991. Those will all have overdrive also. The smaller headlamps were from 89-91. A 2wd Sub will get around 15 or so on the highway, with the A/C on (it is Texas, after all). There were no 2wd Blazers after 1982. The only EFI Blazers you will find will be 4WD (1987-1991). I don't know what difference you will see in mileage, but I doubt 4WD will help it at all.
