I have my 1979 Chevy k10 4x4 with a 350 small block 5.7. It has a a 350 turbo on it that just blew so I want to throw a 700r4 in there for better gas mileage. And I would like the overdrive. But I want to know what all I have to do to put it in there? I know its electrical so I gotta put some type of computer on there. Do I need a brand new transfer case or can I use the one I have hooked up to the 350 turbo right now. Just the whole process of how I need to do this would be nice. Pictures and links help a lot. Thank you!
