I was all whoo-hoo when I got my 5.14 diff swapped for the 4.10 I found. I took it out for a ride and it seems about the same as before. The tech tip I read about here said I could get her up to 55-60 speeds, but it was still sreaming to get to 40. Maybe I missed something. I'm not sure what to expect from a 261 but it seems like it's trying to pull 5 tons. Is it the 3 speed transmission? I appreciate any suggestions. Thanks
