[brothers69c-10]

As the title says my new project will be putting a 350 small block into my brothers 93 2wd s10. I usually fiddle with the 67-72's and the 73-87's so this is new to me. I found a kit that comes with the appropriate motor mounts, headers and radiator for the swap. My main concerns are since it has air will i need to modify the air box to get tall valve covers to fit, will the serpentine setup from the 4.3 work on the 350, which water pump(long or short), andwill all my guages and idiot lights still work since i will be eliminating the tbi. I know i can get the guages to work but i haven't look the truck over that much and was wondering how much of the wiring harness that will need to be modified. The last thing i am unsure of is what transmission is in this darn thing. I'm guessing a 4l60e but i don't know. I know its not a 700r4 for sure. Also will i have to move the transmission backwards at all? I'm sure you guys can answer most of these questions and appreciate all your input.
