10-12 mpg from my experience has always been the average on a 305 V6, my 68 KM-2500 would get that with 4.56 gears which I think is fairly reasonable from a 3/4 ton 4wd truck. Now if you're running a 1/2 ton with 3.07 gears it's possible to do better. Former member Rick Rusconi was getting 19 mpg in his 62 1/2 ton with the 305 V6 equipped with the Holley 500 cfm 2bbl carb running 3.07 gears and overdrive. After the 401M conversion he's getting 17 mpg.
