There is a company I think in California or Washington State that modifys your turbo 350 to bolt up to the early Olds. I have the name somewhere at home. You send them an empty case, they modify the bellhousing, and you send it to a trans shop to have the inner parts reinstalled. Not cheap, but very effective. I plan to do this to my 394 Olds, so I kept the literature.

I'll dig it out and post for you.
