The 200 4r has a 2.74 1st gear which is probably better than the 700r4's 3.06 in your light car with high gearing. Overdrive is a little better with a .67 on the 200-4r to the 700-4r's .70.
The driveshaft length should be the same on the powerglide, short 350 and the 200-4r. The crossmember may have to be moved. I'm sure you already know that you will have to deal with the TV cable and converter lock-up. Both are simple and there is plenty of info on the web. Try bowtieoverdrives. Any 200-4r coud use hardened pump rings, a hardened stator, some larger boost valves, a good 1/2 servo from a Grand National or from aftermarket and a good shift kit. should be able to get all this for less than $300. The trans should live a long life in a 2600 lb car with these mods if not abused and fluid is kept from overheating.
