th350 vs 700r4

[wibilly]

is it true that a 700r4 will bolt to a 205 set up for a 350 by cotting off the tail shaft i realize the 700 is a little longer and will require relocating either engine forward or t case rearward and new drive shafts which i need any way i'm just weiging my options as i only want to do this once i have both tranies and a bopc 350 i'm using a pontiac 400 engine so i have to use an adapter plate to use the 700 i have 4.10 gears and either 29 or 33" tires this will be used as a driver and a tow rig also how much will it take to make the 700 reliable for towing 6-8000 # i would love to hear pros and cons of this combo thanks jim
