I was surprised by your mileage and the mileage reported by 3drburb. I have 79 with a stock 305/2 brl, and get about 12.3 mpg. I would have thought the six would have done better, but mine is a 2wd.
I was pretty surprised by the milage too. I had this motor in a 80 stepside, and got around 15. I think the timing adjustment will make a difference though. It's a full time transfer case, so I guess I probably won't get great milage no matter what I do, but I was hoping for 13 or 14.
