So this may come as a shock to every one, but I'm actually looking for the New Process 540 GL that has the 7.44 first. I have 19.5 rims (33") and a 4.10 diffy. I figure 2500 is not too bad to run the engine at and that'll get me 60 mph. What I want is to make sure I've got that stump pulling torque in 1'st gear. However, if it turns out to be an overdrive, then I can always put my 5.13 gear back in.
I've seen the 6066 gmc guy site many times. An excellent resource. The fact that he is going to put a NP 5 speed in a 3/4 ton is encouragement that I can do it as well on my truck. I figured drive shaft work would be needed.
Now I gotta figure a way to go get it!
