dana 61
The renewed talk about gas mileage and my little turbo 305 project got me thinking about gearing for the 3/4 tons. The best we can do is 3.54 in the Dana 60. While its an improvement over the 4.10 and 4.56 that came with our trucks. I wanted to try a little longer legs. So I dug up a dodge Dana 61 in 3.07. Basically the 61 has a different pinion location so a larger pinion gear can be used. Now I am going to see how this all goes. :
