What rearend do i have?

When you pull the cover just check the numbers stamped on the ring gear. There should be a 43-13 stamped on there if it is a 3.31 ratio.

Well IF it is a 3.31 it definetely HAS been changed, as trucks only go as high (low numerically) as 3.73 so your "ear" or Tach. are off, it already is a good cruising, high speed ratio! [^] Maybe you need a new clutch, quieter muffler or more insulation. In fact a "6" could not pull a Truck with a load without burning the clutch up with that high a ratio!! [:0]

Well it is a Dana 44 w/3.31 gears. Well at least the tag says 3.31 gears. I don't know if they were changed. But I'll keep you updated when i open up the case in a few weeks. Right now I'm trying to find a new motor for the truck. Thanks for all your help guys.

Matthew, I've been running 4.27 gears in Pete for some years now. I don't sense him "screaming" at 55. In fact, Pete sounds happiest over 70. And he's happy to do more[]!
I will say that the stock T-85 3spd is done with 1st gear in a hurry, but that's as it should be. The low gear's for getting started with a load.
I have a truck rear with 3.73 gears in it that I want to put under Pete eventually. My primary aim is to see if I can eek out another MPG or so. Of course, 1st gear will be more meaningful with that ratio, but that's OK with me.[^]

Biggs, what mpg are you getting with pete right now? My dad used to get 18 mpg highway out of the '58 when it was a stock 2 wheel drive with the 3spd OD. I can't remember what gears it had. I think they were 4.27.

I haven't checked mileage at all since the new engine and Edelbrock were put in. It used to get 18 on the hiway if I drove it right.
Pete used to have 4.10s under him and when I switched to 4.27, I really couldn't tell any difference in performance!

depending on your tire hieght i would think 4.27 in overdrive would be around 2750 rpm @ 70. my lark without overdrive travels at that allday
