Re: Rear Gear change for better mpg
Overdrive with a 2.73 isn't a great combo, when using the OD portion of tranny. Keep it in none OD for in town driving. Personally, I have never heard of a 2.73 in the pre 72 years, mostly just 3.08 or 3.73. My 82 had a 2.73 with a T350. I average 11-12 in town and 15 ish on the highway (65-75MPH)
a 3.73 with 700R4 is a good combo for Hiway. Your intown will remain about the same though, least in my experience. As you know, the 250 is not a gas mileage engine.
