The 261 is a great engine. I have the original 4 speed with 4.11 gears in mine and it feels like it is geared too low, I can haul some pretty heavy loads with it and it doesn't feel like anything is back there at all. It pulls hills really well. I have a 3.08 rearend I am going to put in it. I think you will really like the 3.55 rearend. I get about 18 mpg with the 4.11 rearend so I am expecting a bit of improvement. Let us know how it turns out.
