So to swap out the manual for the 700, besides the obvious cooler and floor shifter, can I use stock flywheel? Also what torque converter would be best with 250 i6?

Auto doesn't use a heavy flywheel. It uses a flex plate. I don't much about torque converters, but for someone to answer your torque converter question, I think they'll need to know what gears you have in your rear and your tire height.

An external trans cooler can keep the trans fluid too cool. The trans fluid being too cool is not good either. it needs to either be run thru the radiator to help in cool weather warm up, or run with some sort of a thermo switch/valve to create some heat.

A 6cyl will likely need a slightly higher stall converter than a V8. I would suggest a torque converter for a 6cyl even if it is a V6.

The biggest challenge with installing a 700R4 behind a 6cyl is setting up and adjusting the TV cable to produce the proper line pressures in each gear. To my knowledge there are no TV kits available for the 6cyl stock carb. You will likely have to fabricate something. If the TV cable is not setup and adjusted correctly, you will burn up the trans in a short time.

Great info guys. Trust me I'm all ears. Cupl questions:
-flywheel vs. flexplate. What flexplate am I looking for, or which one fits that will work?
-torque converter. When I go to buy one, which 6cyl vehicles would've had one that would match up to the 700 and whatever flexplate I end up with? I think this is probably an easy match once the flexplate is figured out.
-TV cable. I think I saw somewhere that someone had fabricated a metal mounting plate/system for this. I will look that up and report back when I get home. I'm currently at Barrett Jackson auction at Mohegan sun. So much car porn here it's insane.
