Re: 4x4 trans swap th350 to 700r4

Not be a downer bud, if you're looking for decent mpg you'll never get it pushing 35's. But if you are looking to cruise in OD with 35's you'll want to run 4.56's with your mild small block. All this is not fuel friendly.

yes you can adapt an np205 to a 700r4. There is a few write ups on the forum. Give a quick search and you'll find what output shaft you'll need as well as adapter too.
