I have a 1985 K5 4WD with a 350sb and 700r4. The engine went out on me and I always said I might as well swap it if this happens. I am going to get an overbuild on the 4l60e but other that that I'm not sure what I should pull the engine/trans from in order to get the most bang for my buck. I'm not looking for anything crazy. I want to use it as a daily driver with decent mileage
​​​​​but some power never hurt nobody. What do I need to pull the engine tranny from? Is there anything I should be looking out for and what extra purchases do I need to make it work? I know that if I went straight to 4l60e I would need a transmission controller, do I still need with the LS? Any help is appreciated!
