My 65 C10 230 4spd 3.73 truck runs great. Around 65mph is where is feels like it could use another gear. That NP A833 swap sure sounds interesting. Does anyone know if it is a direct bolt in for one of our trucks or does it require lots of modifying? I'm not sure I'd want to get rid of my tall 4spd truck shifter. I wonder what 3.42 or 3.55 gears would do? I feel like 2nd and 3rd now are almost too low geared and fourth feels awesome until about 65mph.
