th350 swap for 700r4

[Stitch]

I have a 6.2 diesel with a 700r4 behind it. My 700r4 won't shift now and I need two vehicles so I have to fix the truck. I have a th350 sitting in the garage that came behind a 305 stock. I need to k is what I need to make it work for right now. I'll eventually get another 700 but right now I just need my truck. I know I can move the tranny crossmember. And I know the driveshaft will work and the cooler lines will work. I need to know about the vacuum hookup. I read it needs vacuum in order to shift. Also I heard that because it's behind a 305 the stall speed should be close enough. At least for now. I really need to know quick. Thanks guys. I also have a th400 but read that's alot more work. Thanks fellas
